Adalon

When I initially talked to Adalon (silver dragon in Underdark) she told me to fetch her eggs in Drow city, then dialogue stopped. I talked again and she "reminded" me to masquerade as Drow and enter the city. But I can't get into the city. I read a walkthrough that says she is supposed to transform me into Drow lookalikes, but that didn't happen. The same walkthrough indicated that I should have gotten a fake heart from the rebel dude in the Sahuagin city area but he never offered that either. I had to kill the king and priestess and then kill the rebels. (that problem is behind me now, but this dragon thing is keeping me from continuing.) Is my game buggy or am I doing something wrong?

probably a bug, try downloading the official patch. Also, you have to go to the enterance of the drow city incase you thought that you were just teleported there.
