I have given the scroll to dragon.
animation of teleportation was done.
dragon still here:
Is it normal? I guess not, because he becomes red if i think something from its lair and the chest remains unopenable.
Edit: well, i would like to erase this post because... it's scripted and a dialogue starts when talking to dragon...
but I can't.
Edit: oh well, a fedex quest. It's rare in BG.
