ryder

Rayderwyn, also known as "Ryder" (thanks to a nickname from Harley) is an Aves Demon (bird demon). She's not a pureblood, but a half-blood! her mother was a demon and her father was a pure-blood (devil). She only knew her mother and never knew her father, which is weird enough; Either way, she lives in hell and still has the ability to move from realm-to-realm. Since she's only half demon (more than that, actually because her mother had distant demon blood in her; its complicated), she has limited powers with her demon type and is much less powerful- yet, she's still immortal.
Aves demons are considerably short compared to other demon-kinds.

Ryder is friends with Samiael, who is the Prince of Darkness for one of Hell's kingdoms, (like Max is the Prince of Corruption and Satan/Hades' son). and she's basically a "big" sister to him and Max. And unlike Ryder, "Sam" is a Nosferatu Demon (Vampire Demon), so he has different powers and abilities.

Ryder is also friends with Max, who is the Prince of Corruption and Hades' son, and she's basically a "big" sister to him and much of a mother figure despite Max practically having one. The two have never had any sexual relations with eachother, they're too much like family.

She also takes a very big liking to Harley, and thinks the relationship that her and Max have is very healthy for the readhead. Ryder and Sam hang out a lot, actually, and are basically best friends.
