Allies for Bruma

This is an optional quest, however it is directly associated with the main quest and the difficulty of the Great Gate fight. It is recommended you do this quest if you are a high level character and need to fight Dremora Valkyraz and Martynaz on a regular basis. The more meatshields for Martin, the better.

Basically this quest involves going to each major city in Cyrodiil and speaking to the Count or Countess about asking for aid. The story is the same. They cannot spare any defenders until the Oblivion Gate outside their city is closed. Each gate is basically the same more or less with the exception of Cheydinhal's gate where you'll meet up with the Knights of the Thorn.

Defeat the Daedra and grab those Sigil Stones.
