The biggest drawback to undertaking Thieves' Guild quests in Skyrim is that you have to do a lot of dirty deeds that set you off on bad terms with a lot of NPCs you might full well be able to make use of later. This mod helps to offset a lot of that bad blood, particularly during the Taking Care of Business quest. With it, you can choose new dialogue to talk your way out of problems with the applicable NPCs or pay off their debt. Later on, you can take advantage of new dialogue options to speed control and establishment of the guild along in cities of your choosing. This mod doesn't just allow you to fix burned bridges with the Thieves' Guild. You can avoid burning them altogether!
