STYGIAN SUBSPECIES
COMMON SUBSPECIES UNCOMMON SUBSPECIES RARE SUBSPECIES PRIMORDIAL SUBSPECIES


General Stygian Design: While all subspecies have unique traits and looks, there are some elements that are common among most, if not all, Stygian. The following traits are required on most subspecies, unless otherwise specified, so please to to keep them in mind when you're designing your Stygian! These elements include:
Elbow Wings: All common Stygian and many other Stygian have some form of elbow wing.
Side Tufts under the ears. Nearly all subspecies require side tufts.
Front hooves and back hooves. Nearly all Stygian have one or both of these - see subspecies info for details.
Forward facing ears with pointed tips. Common and required for most Stygian.
A deer or canine-like head/skull shape. This means a longer, pointed muzzle.
Indication that the Stygian has fur and looser fluff around the neck, elbow (joining to elbow wings), butt (butt fluff), and where fetlocks should be
Eyes showing three parts: Sclera, iris, and pupil.
There may be some variations among the subspecies, please see individual subspecies information below!

[Restricted] Mimic Subspecies:

Traits default included:
Species Unique Traits: Mimic body (dripping shadows), Stygian 'coat' (resembles a regular Stygian), mimic antlers (dripping shadows), elbow wings (drooping), deer tail.
Mimic Stygian have a very deer-like shape, from the legs to the head, to the tail. They're trying their very best to appear to be very normal Stygian!
Traits that can be replaced or modified with potions: Tail (can be replaced but not removed), antlers (can be replaced or removed), elbow wings (can be another type of wing but not removed), Stygian ears (can be modified).
Mimic Stygian all have a body made out of shadows. These shadows will always be very, very dark (dark gray to black), and should drip slightly and the legs should be semi-tranparent closer to the hooves (see reference image above). The mimic body (shadow) cannot be affected by any traits save for Multiple Eyes, Exposed Aether, Corrupted Aether, and Hollow Crater (hollow crater will always have dark, shadow insides). The shape of the mimic body (deer shape with deer legs) cannot be changed.
Mimic Stygian always have a regular Stygian 'coat'. This coat fully covers their head and back, and all or most of the neck (see reference image). This gives them a very normal Stygian type head, neck and back. The coat should be fluffy, as they are trying to mimic Stygian fluff, after all! The Stygian's elbow wings will attach to this coat, rather than to the mimic's leg (see reference). The fur coat cannot be removed, nor can it be made to be see-through in any way.
Mimic Stygian come with a short or medium deer tail. This tail attached to the fur coat of the Stygian, rather than the shadow body. It can be changed to other types of tails, but the tails will always attach to the fur coat. Traits such as wings attach to the fur coat only, and do not expose the shadow underneat in any way.
Most traits, for example, Glowing Markings, Crystalline Growth, Body Sparkles, Long Fur, Foliage Takeover, etc., will always attach to the fur coat of the Stygian, and have no effect on the mimic's shadow body. Shadow Weaving cannot be used to change the limbs of the shadow body, however, it can be added to other traits on the Stygian.
Mimic Stygian can have antlers that are made of the same material as their shadow body. If a potion is used to change their antlers to another type or to horns, they will no longer appear as the mimic's shadow body - rather they will take on normal antler/horn appearances.
Exposed Aether and Corrupted Aether can affect the mimic's shadow body. This will turn the shadows into exposed aether. However, the exposed aether will not carry over to the mimic's fur coat in any way. This means the Mimic Stygian's head will not be turned to aether.
Some traits cannot be applied to Mimic Stygian at all. These include Object Head, Front Paws, Fetlocks, Fin Fetlocks, Glass Body, Elemental Insides, Shapeshifter, Elemental Outer Body, and Skeletal Replacment. Other traits cannot be used in such a way as to change the base structure of the mimic's body.
Traits that cannot be entirely replaced: quadrupedal, side ear tufts, general face shape (deer or canine-like skull), elbow wings, mimic body, Stygian fur 'coat', deer shaped legs.
Default Traits that can be inherited: Elemental Aura (if not replaced by aether), Elbow Wings, Antlers (if present on Stygian)

CLARIFIED due to confilict with Treatlings: Page Stygian have human shaped skulls/faces, but they still have a thin coating of fur on their face. While this fur can be any color, it should not appear to be missing or flesh-like. It should always have a fur texture or tone to it, and would usually be the same color as the rest of the stygian's fur. While the fur on the face can be flesh coloured, there should always be some indication that this is fur and not actual skin (keep in mind that this colouring should show up on other alt forms if this is the case).
Page Stygian should have their little hooved feet be visible.
Traits that cannot be entirely replaced: Bipedal, side ear tufts, general face shape (flat human-shaped skull), back hooves, book/paper based accessory, clothing covering page from chest to knee, and extra fluff at the wrists and neck.

PRIMORDIAL SUBSPECIES BACK TO TOP
Sometimes a Stygian can evolve into a Primordial Stygian! This requires them to have the Primordial Trait, gained either through breeding or by using a Primordial Potion.
Any subspecies can evolve to a Regular Primordial - otherwise they are restricted to their own subspecies when evolving.
For more information on Primordial Evolution please GO HERE!


Primordial Regular Subspecies:

Default Traits that can be inherited: Regular Subspecies, Mane Fluff, Colored Sclera
Primordial Regular β (Beta) Subspecies:

What is a primordial β (beta)? Basically, when your Stygian is evolving from regular (or another species) to primordial, it can choose the regular primordial form, or the primordial β (beta) form. It's basically an alternate option to the original primordial form!
  • A Stygian that is already regular primordial regular cannot swap to β unless they have another primordial potion, rewind ticket, or alt-myo ticket.
  • A Stygian that already has the primordial trait can use an alt-myo to turn it into a primordial regular β.
  • A Regular Stygian with no primordial trait can use a primordial potion to select if it wants the regular primordial or the β version.
  • A Stygian jar that has primordial inheritance, if the subspecies of the jar is regular, or if a Stygian myo is a regular subspecies and has a primordial potion picked for it, can pick regular or β form.
Traits default included:
Species Unique Traits: Fully skeletal body, boney elbow wings, Stygian skull, hollow/empty eye sockets.
Traits that can be replaced or modified with potions: Tails can be added and changed with the proper potions.
Primordial Regular β Stygian are fully skeletal, and rather deerlike. The torso and legs should always be a deer shape and hooved. The skull and skeletal structure should be as close to the reference image above as possible.
Primordial Regular β Stygian have empty/hollow eyes in the main eye sockets of the skull. Glowing eyes, cosmic eyes, coloured sclera, and other eye affecting traits cannot be added to these main hollow eyes. (They can be added to other eyes added to the Stygian, however, if applicable.) Other traits cannot be used to mimic eyes.
Primordial Regular β Stygian come with a short/medium tail. It can be skeletal or it can be fluffy or feathered (following the normal short/medium tail rules). The tail can be changed to other types of tails, as long as it follows the rules of that tail type. Tails do not need to be skeletal.
They will always four deer-like legs, thin and ending in hooves. Front paws cannot be added to change this. Also, fetlocks and fin fetlocks cannot be added to legs.
The bony elbow wing should be similiar to the reference image (like a simplified bird wing). Elbow wing modification cannot be applied to change the wing type, shape, or add feathers or membranes - it will always resemble the reference image. Elbow wings plus can be used to lengthen the elbow wing.
Traits such as back wings (any type), long hair, spine fur, mane fluff, and foliage are a-okay to add.
Elemental Aura cannot be used to infuse, replace, or change the texture of the skeleton. It can, however, wrap in and through the rib cage and the skull. For the ribcage, it must also be outside of the ribcage in some way. In the case of the skull, the elemental must also leak out through the eyeholes and mouth.
Elemental Insides can be applied to Primordial Regualar Beta, however it only affects the inside of the bones - where the marrow would be. It must be visible, using either small cracks or another trait such as fragmented body.
Ears and modified ears (and ear tufts) cannot be added, unless using an object head potion (under usualy object head rules).
The Skeletal body cannot be removed, replaced, or changed in any way. The ribcage and legs will always be based on deer as seen in the reference image above. Multiple limbs, extra mouths, glass body, hollow crater, and other body modifying traits cannot be applied to Primordial Regular β Stygian. Elemental Aura cannot affect the texture of the skeleton. Additionally, long fur (guardian trait) cannot be added.
Traits that cannot be entirely replaced: Quad form, general face shape (deer or slightly canine-like skull- see reference above), skeletal body (no modifications at all), bony elbow wings, four hooved legs, and hollow/empty eye sockets.

Primordial Bat Subspecies:

Traits default included:
Species Unique Traits: Aether wing arms and tail, connected together as a mantle of aether. Large, single tipped, bat ears with bat ear insides.
Aether arm wings and aether tail are connected to each other by an aether mantle that covers the entire back of the primordial bat. This aether should always have a foggy or misty texture, with a galaxy or starry pattern only. It can be any colour, and be multiple colours. The hands themselves should always be large and made with 4 long, vaguely claw-like digits, like in the reference image above. The ends of the wings very lightly taper down into mist before forming the tail. (See reference image)
The aether tail is connected to the arm wings and mantle. The tail will always be long, thin and end in a simple spaded shape. While the shape of the tail cannot be modified or changed, the tail can be supersized or multiplied (must retain the spaded shape).

Traits that can be replaced or modified with potions: Tail (can be added to the fur coat only), Stygian ears (can be modified).
Primordial Mimic Stygian all have a body made out of shadows. These shadows will always be very, very dark (dark gray to black), and should drip slightly. The legs should be semi-tranparent closer to the hooves (see reference image above). The mimic body (shadow) cannot be affected by any traits save for Multiple Eyes, Exposed Aether, Corrupted Aether, and Hollow Crater (hollow crater will always have dark, shadow insides). The shape of the mimic body (grendel shape with hooved hind legs) cannot be changed.
Primordial Mimic Stygian always have a Grendel-like Stygian 'coat'. This coat fully covers their head and back, arms, and all or most of the chest (see reference image). This gives them a very normal Grendel Stygian type head, chest, and arms. The coat should be fluffy, as they are trying to mimic Stygian fluff, after all! They will always have extra mane fluff around the neck and chest (see reference). The fur coat cannot be removed, nor can it be made to be see-through in any way.
While they do want to appear to be Grendel Stygian, Primordial Mimics have not mastered the Grendel's standard long back mane. As such, they do not come with a long back mane or anything similar. (Hair can be attached to the head with a potion, of course!)
They will always have dark sclera to match their shadow color!
Primordial Mimic Stygian will always have large arms that end in large paws. These paws will always have 4 digits and large claws. See the refrence image for an example.
Most traits, for example, Glowing Markings, Crystalline Growth, Body Sparkles, Long Fur, Foliage Takeover, etc., will always attach to the fur coat of the Stygian, and have no effect on the mimic's shadow body. Shadow Weaving cannot be used to change the limbs of the shadow body, however, it can be added to other traits on the Stygian.
Exposed Aether and Corrupted Aether can affect the mimic's shadow body. This will turn the shadows into exposed aether. However, the exposed aether will not carry over to the mimic's fur coat in any way. This means the Mimic Stygian's head will not be turned to aether.
Some traits cannot be applied to Primordial Mimic Stygian at all. These include Object Head, Fetlocks, Fin Fetlocks, Glass Body, Elemental Insides, Shapeshifter, Elemental Outer Body, and Skeletal Replacment. Other traits cannot be used in such a way as to change the base structure of the mimic's body.
Traits that cannot be entirely replaced: bipedal, side ear tufts, general face shape (deer or canine-like skull with a shorter muzzle), mimic body, Grendel Stygian-like fur 'coat', hooved hind legs in a standard Grendel shape.

CLARIFIED due to confilict with Treatlings: Page Stygian have human shaped skulls/faces, but they still have a thin coating of fur on their face. While this fur can be any color, it should not appear to be missing or flesh-like. It should always have a fur texture or tone to it, and would usually be the same color as the rest of the stygian's fur. While the fur on the face can be flesh coloured, there should always be some indication that this is fur and not actual skin (keep in mind that this colouring should show up on other alt forms if this is the case).
Page Stygian should have their pawed feet be visible.
Traits that cannot be entirely replaced: Bipedal, general face shape (flat human-like skull), back paws (3 digits), floating card accessory, clothing covering page from waist to upper thigh, and extra fluff at the wrist and neck, side ear tufts.
