Dragondog:
We have the standard kender that we all know and love....
And then Membakar, a now dead red dragon, did some very foul stuff, some kender witnessed the event and were so affected by it that they're no longer the fun loving creatures they once where. Hence, afflicted.
Basically, they are a variant race of kender.
Oh I see, you mean they act like 'normal' people. ;)
@Eucharista: Yes, the poor lighting on the cgi may lead to that conclusion :) I always have problems remembering names of actors/actresses, except for a few.
