1 Draak: Draak spend time to teach young cold bloods in ways of world past swamp.
2 Alvissa: Teaching the youth of your race. That's very noble, Draak.
3 Lambert: What did you teach them about hobbits?
3 Draak: Not to step on.
4 Lambert: That's... thoughtful.
4 Draak: Get stuck in claws. Hard to get out.

In the years between the last adventure and this new one, all of our heroes have ben up to lots of different things, some of which they reported here. But all we heard of what Draak had been up to is that he did some work in Lambert's garden. Being the cosmopolitan and well-rounded lizard man he is, of course he's been doing other productive things as well.
