Windward Ruins is a small outdoor Nordic ruin southwest of Dawnstar, inhabited by skeevers.
It is one of the three ruins visited for the Destruction Ritual Spell quest. With the Vigil Enforcer Armor Set Creation installed, Azarain's corpse can be found here.
There is a central circular area surrounded by an enclosed outer passage. It is guarded by two skeevers and contains an adept locked chest behind a tilted pillar by the outer wall of the passage. During the Kyne's Sacred Trials quest, you will find a larger-than-life, ghostly skeever within the ruin. During the Destruction Ritual Spell quest, you will need to activate a plinth in the central area to place the book Power of the Elements received from Faralda, then cast a flame spell at the plinth; you will then advance the quest and receive the clue to the second location. There is a snowberry bush in the central area.
