The torn fragments have been pieced together to form a map! But there is yet one more piece to this puzzle....

Description
Stage 1
Stage 2

'The fragments you brought me are most assuredly a map, but it seems there is yet one more piece to this puzzle. This passage here mentions an ensorcelled candle whose flame is used to find a hidden door. Sadly, the candle seems to have been stolen by a hobgoblin leader named Tuzugrák.

'Tuzugrák and his ilk are holed up in Anatrâd, the ruins north of here. Go, retrieve the candle, and defeat Tuzugrák and his captains.'

Tuzugrák and the hobgolins can be found holed up in Anatrâd.

Lore-master Rúni has asked you to defeat Tuzugrák and his hobgoblin captains, and to bring back the stolen candle.
