Sees-All-Colors is the Guildmaster of the Fighter's Guild. She has created the contract involving the Anchors and stopping the Daedra invasion.
Later in the storyline, it is revealed that she murdered Jofnir because he was unwilling to stop the anchors, and that she is a priestess of Meridia. Ultimately, it is up to the Vestige to decide her fate.
If spared, she will survive as an advisor to the new Guild master, or she will be executed for murder.
Sees-All-Colors has had Doshia's Journal translated. From it she believes she may have discovered information relating to the mysterious Mortuum Vivicus. The Vestige have been asked to report to Guildmaster Sees-All-Colors at the Guildhall. They should talk to her as soon as possible.
