This is the very same priestess, Hekta, and one of the most powerful Drow in the game. The goggles are a great help here, as is Elminster himself, who needs multiple relics housed in this very temple.

Using the Drow race during the character creation will also allow you a free pass into the goblin camp. Fighting the goblin guards or sneaking past them is dangerous, so it is better to avoid them.
