The Nerdventurers barely escape from being crushed and find themselves trapped in the innards of a leviathan. After doing battle with the sentient contents of its stomach, they find their way to its gigantic, beating, black heart. There they are challenged by Razazel, the Lifeblood of Dagon, and her blood and electric elemental henchmen, but with Lightstrike's vorpal boomerang and Mherren's fire elemental form, they win through and still the beating heart, before finding teir way to the mouth and breaking through its baleen. In its death throes, the beast breaks through the planet's crust and swims up into the air, before coming crashing back down into the rugged terrain of the Hinterlands. Lightstrike and Haji Baba are unscathed, but Zellingar is severely wounded, and Mherren and Zimlok are knocked unconscious. Healed by the periapt and Lightstrike's quick thinking, they leave Dagon's mountain-like carcass behind and make their way to a rocky shelter, where they make camp and enjoy the feel of the fresh air and natural light. In the distance they can hear a voice singing a strange song, and overhead they see a portentous, bloo- red comet in the twilight sky.
