Remove every gem from your inventory and store them (ruby, sapphire, diamond, etc etc) and cancel the quest. Go to Vex or Delvin and they have an option to drop that quest and give you some bullshit speech. Then you can select another quest and hope it's in the city you want.
If you have gemstones in your inventory though, every time you drop a quest they take one. Assholes.
But that seems extremely dishonest. Muhahaha I'll do it. Thanks for the advice.
You forget that this isn't just some brutal sport where everyones out to kill each other. Its much more like a game of physical chess.-looney liam
