Auntie May is the last surviving member of The Wives of Night, and has allied herself in some way with a cult operating out of Lancetide.
A book was published about Auntie May and her sisters many years ago, and only a fragment of it seems to remain – so a lot of May's past is a mystery.
She has encountered The Hag Wranglers several times and evaded capture or death. The first time she teleported a member of the cult to safety, the second time she entered Lark's dreams, the third time she attacked part of the group alongside Aeon Darknight, and the fourth time she fought them on the beach of Lehen Kartzela before escaping.
