The brave adventurers were all contacted by an obscure and enigmatic old Archmage, who warned each of them of a dark abomination that threatened to awaken and return to the world to sign its doom. After warning them of this horrible evil, he requested their aid and after each gave a confirmation, he teleported them to the ruins that held this beast.

There, they were attacked by a corrupted Black Dragon whom they easily slew. Next, they were beset by a crafty Red Dragon, and after a difficult battle, managed to slay it as it fled. But more awaits them in the Temple of That Which Hungers….

What happens next?
