Dynari Amnis is an Imperial member of the Thieves Guild who lives in the Talos Plaza District.
During the quest Misdirection, her house is used as Methredhel's headquarters. Dynari's basement leads to the Talos Plaza Sewers which also connects to Amantius Allectus's house from the quest May the Best Thief Win. She has a small amount of gold on her, but little else of value.
Because of the recent events, Hieronymus Lex has pulled guards from all over the Imperial City to the Waterfront in an attempt to root out members of the guild including the Gray Fox.
