Erymos: Shadows of Primar (Feb/14 - Dec/14)
"Thank you for waking me. Now prepare your sacrifice."
Agera was a hell harpy or succubus or some such bullshit, summoned by the Cult of the Unseen. Lester, amongst others, was sacrificed to bring about her arrival. She was a member of elite assassins known as Shadowface, who act in service of no god. Agera was known by some as the patron demon of duplicity.
Her ash was purple, and was made into a sweet demon-seeking box.
