Thanks for your reply. Now im stuck with thief guild quest and new blade for tsubaki. For thief guild I'm already use all my teleport stone to thief guild and i can't go back there again. And for tsubaki new blade i dont know where to find a mithril
You can always get back to the thieves guild the same way you got there the first time, through the underground way when you take the stairs down in the storage building in Thremten.
Mithril can be found in several dungeons in Dorgania. You need to advance the main story line to get into Dorgania.
