This is the first class quest you will undertake as a rogue. It's purpose is to introduce you to your class trainer.
You must complete the quest  before you can access this one. Additionally, this quest is limited to trolls only.
Ah, while you were gone a tablet came for you, <name>.
I am Rwag and I am responsible for training the rogues, thieves, and cutpurses here in the Valley. I'm the one the Hand will turn to if you're not ready for what's to come. But don't worry, the Hand won't be controlling everything you do, but it would be wise to work with them if they have need of your talents.
Until such time comes, you'll be under my tutelage. I will show you the ropes as some folks say. Whenever you feel prepared, come to me and I will see about training you further. Until then, practice your skills and keep them honed to a razor's edge. You'll never know when you'll need even the most insignificant ability.
