Well, think of anthro tall birds of the Corvid family with a dark plumage, a black scalera with either a pair of eyes, or 3 eyes or extremely rarely with 2 pairs of eyes, they also have horns on their head, extremely rarely with 2 pairs of horns. The shortest variety is 4 foot and the tallest is 9 foot (although my feathersona is 9'1 foot tall). The horns have a few shapes, they also have technically speaking 4 biological sexs; male, female, intersex and genderless and are either naturally pansexual or bisexual and may be polyamorous.
They live on a planet called Taloon-4c which is in a binary star system and the planet is has the same percentage of nitrogen in its atmosphere as there is oxygen on Earth's atmosphere. Void Ravens breathe in nitrogen.
They're far more technological advantaced than that of humans.
The rest, well...it's a lot.
Another thing to note is that the naming scheme is...Say, similar the Kenku race from Dungeons and Dragons. But that's the non-Taloonian name...The rest....
(Considerimg they're a semi-open. Meaning with my permission, you may create a character. Or with Simo's but...Simo has to request my approval)
Well...It's complicated
