The Player Characters have defeated two of Milton Drac's minions: Milos and Verlaine. Considering them a real threat, he keeps his friends close and his enemies closer by inviting them to a ball. There, Milton attempts to implicate them in a clumsy assassination plot, but Vlad Martell (who learned from his incident with Cunegunda) is far too savvy. A mysterious apparition appears, foretelling of how only Yig can stop the Unspeakable One.

Thuron directs to the PCs to an ancient Temple of Yig, which was buried where Black Dog kept his treasure. IlmarÄ— Galen charms Gareth into telling her the location of Black Dog's cave and it's not long before they're battling for their lives against ghosts, traps, and Black Dog himself.

After retrieving various artifacts of Yig, Beldin Soulforge sacrifices some of his life force to manifest the Jade Serpent of Yig and lift the curse. Then the PCs escape, moving as quickly as they can to stop Milton's plot...

But whas is Milton's plot? With the lighthouse, Milton's Folly, fully operational, Freeport parties like mad at the grand opening. Then it becomes clear: Milton plans to project the Yellow Sign before the crowd, driving them completely bonkers. With Vestalanium still fresh in their minds, the PCs move urgently through the lighthouse.

After tangling with N'Tal, they reach the top just as the Yellow Sign appears. Seconds pass as Kham val'Abebi grapples with Milton Drac. Finally, the Jade Serpent of Yig is placed on the projection crystal. The Valossan energy projected from the Jade Serpent causes the ssanu egg Kham found to hatch, and the baby ssanu immediately imprints upon him as "daddy." Freeport is momentarily silent...and then erupts in wild cheers as everyone assumes it was just part of the fireworks.

The madness of the Yellow Sign was dispelled just in time.

Or is it?
