Eric and Bobby retrieve a box for Dungeon Master. Dispite the fact that they were under strict orders not to open it, Eric gets curious. Just as he pulls the pin from the lock, Dungeon Master appears and warns Eric to place the pin back in place before it's too late. But Eric is taken by surprise when a force blows the top of the box off and releases He Whose Name Cannot Be Spoken. He is Venger's master, pure evil, and a powerful entity.

The kids stumble upon a young man, sick from exhaustion and hunger. His name is Kosar and he has escaped imprisonment by a demon called Queen Seris. She wanted Kosar out of the way so she can remain in rule, fearing the 1000 year-old ancient prophecy that must be fulfilled by a 'child of the stargazer.' The legend states: And on the night of star fall, the child of the stargazer shall come from a faraway land to stand in the Temple of Light. The demon shall be vanished and the child shall journey home. After an attack to take back Kosar, the kids start their journey to the Temple of Light.

After another attempt at getting home is foiled by Venger, the frustration is too much for the kids. They decide to take the fight to Venger and finish things once and for all. Their idea: Tiamat - Venger's mortal enemy. When they disregard Dungeon Master's next mission to embark on their own, he advises against it and then indicates where they can find Tiamat.

They then find an oasis, that's inhabited by a clan of monsters. When the monsters have them surrounded, a traveller by the name of Ramuud comes and saves them. He then leads them away from the cursed oasis to his own encampment. Ramuud then explains that long ago his daughter, Aisha, was kidnapped by the Nightwalker and is being held prisoner at the City at the Edge of Midnight.
