Tonilia is a merchant specializing in stolen goods. She hangs out by the Thieves Guild headquarters.
When S'oggy and Delvin were sitting down discussing the details of their mission, Tonilia rudely pushes S'oggy out of his seat to sit down in his chair. S'oggy and Delvin has to talk very far from each other and Delvin's deep voice does not carry far. S'oggy misses most of the conversation.
