Hi, I'm at the step, when I'm asking Byron Ambrosine about questlevels. I asked him, he tell me something about it, but what I should do next?

If you want to know more about levelquests, the actual quest-room is located east from byron, shouldn't be too hard to find.

If you are stuck in the room, there's a door there that leads south, it does not show as an obvious exit when the door is closed, but you can still walk through it.
