From the front of book:

Impiltur has been plagued by goblins throughout its long history. Now, an army of spellscarred goblinoids organized into a formidable force by a powerful bugbear waits beneath the surface of Impiltur in the Underdark to crush all of Impiltur. Adventurers learned of this threat and now the Grand Council wants this beast taken out the old fashioned way, quickly and quietly with a dagger in the dark. A Living Forgotten Realms adventure set in Impiltur for characters levels 11–14. Second and final part of the Blue Fire Goblins quest started in IMPI2-1 Goblins From Below.
