The House of Deros Frist
The isolated tower of the wizard Deros Frist is an example of a typical tsochari incursion into the human world. This short adventure site describes the lair of a tsochar noble that has successfully replaced Frist, a local wizard of some renown. The tsochar Yikk Tasst now pores through the wizard's libraries and spell books, eagerly absorbing all the arcane lore it can.
