One of the cool things about Graal is seeing all the other players, so it doesn't really make sense for the tutorial to be in such an isolated location.

That being said, you kinda gotta question the need for a tutorial in a game like Graal where everything is really self-explanatory. Maybe make a brief quest that requires you to do stuff you would normally do in the tutorial (have a switch that you need to shoot with an arrow, etc.). Then you can give little hints (like "press the arrow button to shoot the switch") while requiring the player to actually do something. The way the tutorial is set up just feels like a laundry list of several pointless things you have to do.
