(NB: this adventure is set in a desert in the broader 'Nentir Vale' world, but not the Nentir Vale itself) Eladrin raiders led by the Half-Elf Emrett Mazrid have been trying to uncover the secrets of immortality. Disgraced academic Mazrid has discovered an obelisk in an oasis guarded by a sphinx, and is preparing to sacrifice their academic rival Voor as part of the ritual. Save Voor, the obelisk, and the oasis!

But those stories pale in comparison to a new threat under Mulmaster, one brought to light by a strange and disturbing corpse recently found. It is up to you to learn the terrifying truth of what lurks below.
