Shashpilamat is a Daedric ruin found in the Azura's Coast region of Vvardenfell. The House Telvanni storyline quest, Objections and Obstacles, involves this location. It is not marked on the map, but is one of the locations you need to visit for the Daedric Explorer achievement.
This location contains generic bandit enemies, as well as Khajiit slaves. The lorebook, The 36 Lessons: Sermon 20, can be found here, as well as at least one Luminous Russula.
