By the time Lith woke up, every member of the expedition had returned. They had mustered the courage to check on the outcome of the battle only after they had realized that they had no way to open the closed doors.
Quylla returned their items to them from Ellkas's dimensional amulet and Phloria took Morok with her to explore what remained of the room. Gaakhu was still alive, and she couldn't afford to leave their back exposed to the alleged traitorous mage.
She didn't have to search for long since the missing Professor's corpse was waiting for them in the next room. No one would even know that just like the Odi, their slave seal on their victim's life force required the Mana Reactor to work.
The moment the device had run out of power the spells engraved in Gaakhu's life force had consumed her vitality in an attempt to prolong their existence. Phloria stored the corpse in her dimensional amulet. Traitor or not she didn't deserve to be left there to rot.
