gender-archival:

Abyssinfernal was coined by Tumblr user sapphire-crimson-claw-archive on January 31, 2018.

Abyssinfernal is described as “a hellgender individual of the void, with no sense of gender or attachment to masculine or feminine energy. Is nevertheless powerful, vengeful, and sexual of a being.”

There wasn’t a flag in the original coining post.
