The Immortals After Dark

Series contains 20 primary works and has 21 total works.

Every creature thought to be mythical—from the violent sorority-house Valkyries to the fey slave overlords to the hell spawn from each brutal "demonarchy"—all exist.

These immortals call their world The Lore.

You may have had a brush with one of Lorekind already. They secretly walk among us, but they war among themselves. Each faction has its strengths, weaknesses, and age old prejudices against the others. 

Every five hundred years, the Accession, a battle for supremacy, rages. That time is now. . . .
