Open to Kleptomaniacs.
The Thieves Guild is the only places where you can train to learn thieves skills. You cannot buy these moves in stores. Thieves techniques are purchased with money, and learned with experience.
When you find the Thieves Guild building in each of the towns you may access the thieves guild techniques available to you.
Unlike with magic, all techniques will be available to you in every thieves guild building. Unlike with magic, there may not be a thieves guild in every town, especially in very small rural areas, particularly meticulously law abiding places, and most military run forts .
Like mages and the book stores, you will come to thieves guilds to purchase new techniques. Some techniques will require an additional "trade", to prove you are a qualified and willing thief. Most can simply be bought. Thief techniques will be listed below as they become available. Check back here often.
