So, you want to create a DarkWing. Good news is, you can consult this guide for help!
Remember: your DarkWing is the product of your own creativity! Think of this as a way to help your own creative process along when you're stuck.

T Y P E
Your first decision should be what type of DarkWing you want to create. Is it a normal DarkWing? Or perhaps a Lumo? Once you've decided that, you can move onto the next step.

N A M E
After you've decided your DarkWing's type, you need to choose a name. The DarkWings, like any other tribe, follow a specific naming convention.

Name (Basic)
A normal DarkWing's name can be a form of or other word for darkness. This can also be in a different language, or can be the name of a dark thing in nature. It can also be associated with caves, or a natural weapon/something associated with said natural weapon.
Examples: Umber, Night, Stone, Talon, Slash

Name (Lumo)
A Lumo's name can be a form of or other word for light. Just like a DarkWing's name, it can be in a different language, or the name of a light thing in nature. It can also be associated with more abstract things like part of a personality; think Tiefling 'virtue' names from D&D.
Examples: Luminous, Flicker, Perseverance, Legacy

Name (Half)
A Half's name is always something you gain from one of your senses, although is most commonly related to hearing. Depending on the Half's main scale shade, the name is typically either more positive or negative; a primarily dark Half may have a more negative-leaning name compared to a primarily light Half.
Examples: Silence, Boom, Bright, Rough, Bitter

Universal Rules
No DarkWing may have 'moon' or 'Star' in their name.
Twins will often have names that follow a similar concept and/or alliterate (ie. Princes Tooth and Tear).

T R A I T S
When deciding the appearance, personality, and abilities of your DarkWing, you first need to answer one question:
What is their social status?
Typically, a royal or Mage will have the highest status. Below them are high-ranking guards and soldiers, followed by nobles and religious leaders, then by normal DarkWings. Social status determines a DarkWing's wealth, as does their or their family's occupation.
With social status in mind, follow the DarkWing appearance and abilities in I || General Info.

Abilities
There has never been, and never will be, a DarkWing animus.
With that out of the way, keep in mind that unless your DarkWing is either a Mage or a royal, the most they will be able to do in terms of abilities are the ones described in I || General Info.
As for a Mage or royal, you can be as creative as you want. However, their abilities are limited to their scale shade; a basic Mage or royal will only have dark-based abilities, a Lumo will only have light-based abilities, and a Half will have those of their primary scale shade and a much weaker form of their secondary shade.

Personality
Every DarkWing is different, so you have plenty of freedom here. However, keep in mind that DarkWings are a religious society, and most never leave the underground cities they call home.

And there you have it! If you have any questions, don't hesitate to ask.
