Abyssal Plague

The Abyssal Plague Series Event In a dark dimension beyond the known planes of existence, the Chained God thirsts for freedom. Infusing his will into the residue of a long-dead universe—scarlet liquid shot through with veins of silver and flecks of gold—he sends this liquid crystal between worlds to prepare his way. But his will is not the only force that drives the Voidharrow.

Imbued with the power of the Voidharrow, the dragon Vestapalk creates a horde of demonic minions to spread the Abyssal Plague across the Nentir Vale. But the threat is not contained within a single world: Faerûn and Athas must contend with their own outbreaks of tainted demons and virulent plague. Will the Voidharrow consume the multiverse? Will the Chained God break free? Or will the heroes of the age put a stop to the Abyssal Plague?

The Abyssal Plague is an event that spans the worlds of Dungeons & Dragons. Seven novels and a five-part novella tell its story across three worlds, and its insidious reach extends into roleplaying products such as Monster Vault: Threats to the Nentir Vale and future seasons of D&D Encounters.
