Aisha is a middle aged halfling witch. She used to have a coven of 5 other witches, but only she remains. The coven is now infested by insectoids and she has locked herself in the supply room. There are not many options left, but making a suicide run isn’t high on her list. She has limited supplies and is hoping for a miracle. By nature she is an extrovert and a fatalist, but possesses a strong charisma. She is not a loner, though all witches tend to limit their associations with the mundane world. In her youth she was a house slave of a human family in the metropolis of Gory, and she hated every moment of it. Witches always focus their powers on one aspect of magic or another; hers being transmutation and transference. The grotto is a lush underground cave heated by a hot spring. It’s limestone walls sheltered the coven for centuries, but now the insectoids have burrowed their way in, and it’s usefulness to Aisha has passed. This expansion includes: Hero: Aisha, the Uncanny Shapeshifter. Including custom hero deck, shields, and stat sheet. A new type of enemy: The Tharnix. Full sized double-sided map board. Standalone campaign of 5 scenarios. 4 extra treasure cards by guest designers. Special wound card designed by Tristan Hall.
