Some lady wanted Kal to join a cult?
Sister Garaele at the shrine of luck in Ruins of Phandalin.
When in Elvenroth, Kal meets Enhana. She is sceptical but tasks Kal to bring a package to her contact in Ravenforge if she wants to join the Cult
From the quest log:
Sister Garaele asks for a word alone with Kal, and reveals she is a member of The Veiled Protectors, whose motto is “Out of darkness, we bring light.” She offers Kal to join the order, which Kal first declines. She does, however, go on to consider it, and is told she might find more information at The Generous Queen In ad Elvenroth. She should ask for Enhana, and she might give Kal an introduction to the order.
