Deravan listened to what Robert just said, and nod, looking down a bit.
"Ya...we kinda did explore a cave full of it, and we ended up alright. That is really weird? Maybe that dragon got hit by an attack that was doing this to him? Maybe he was hit by the real source of this dust... not sure." he then says, looking at him before breathing deeply.
"Let me get us to the house of that dragon. I kinda have some sense of orientation at least. No offense Robert." he says before moving forwards and going towards where the dragon was before. At least they got the egg now. Although... a dragon started off by stealing it and then that troll... who was stupid enough to steal a dragon egg anyway. When he though about it, the group will need to be on their guards. If the dragon that did this decide to go and attack them for taking the egg back, this could be bad.
