Yaztaramz is the home of a Telvanni wizard conducting research on the Dwemer.
It lies on the coast between Helnim and Firewatch, being northwest of the Daedric Shrine of Onimushili and the other Dwemer ruin of Ratharzak. The occupant, Rethyn Verelnim, has left rather a large number of Dwemer Centurions alive, and they will bar your passage. Rethyn himself features in two Fighters Guild quests, both of which may involve a visit to this location. He himself resides at the top of the ruin's tower. A note, Note to Rethyn Verelnim can be found on some drawers in his room, and will prove helpful in unlocking the full reward for the quest Darythi's Change of Heart.
