Location from Curse of Strahd by Tracy & Laura Hickman, Chris Perkins / Wizards of the Coast
Lady Wachter's estate in Vallaki — a house of secrets where cult meetings masquerade as book clubs, a mad daughter crawls in the attic, and a dead husband lies preserved in the master bedroom.
Wachterhaus is an elegant townhouse in Vallaki that hides horrors behind its respectable facade. In the parlor, Lady Wachter hosts her 'book club' — actually cult meetings devoted to Strahd. In the master bedroom, the embalmed body of her husband Nikolai lies in bed, dressed and arranged as though merely sleeping. In the attic, Stella Wachter crawls on all fours, mewing like a cat. The house is immaculately maintained, which makes its secrets all the more disturbing. Every surface is polished, every curtain drawn just so, every piece of furniture in its proper place. The disconnect between the house's order and the madness within it is pure gothic horror.
