Vampire Mistress

You serve the Vampire Queen in secret, and secrets like that never stay simple. The moment she vanishes on some unexplained errand, her daughter seizes control of Blackthrone Keep and puts you on a short leash, spoiled and venomous as she is.

Officially you're stuck taking orders. Unofficially you're free to wander the keep, dig into the queen's disappearance, and chase down the artifact she left behind, not knowing if it'll shift the balance of power in the keep or just land you in the new mistress's bed.

It plays as a point-and-click sandbox: explore rooms, needle the women running the place, and work through whatever they demand of you in exchange for information. Nothing fancy, just a fortress full of women who all outrank you and a servant trying to find out why.
