Ulamog, the "Infinite Gyre" is one of the three Eldrazi titans and the monstrosity whose half-forgotten name came to be known as the Zendikari merfolk sea god Ula.
Ulamog is the Titan of Consumption. He and his brood consume living and unliving matter alike, and drain mana and vital energy from everything in the vicinity like a maelstrom. His processors transform the consumed energy into spell-like effects that defy the understanding of Zendikari mages. They leave the white chalky latticelike structures in their wake. Everything including water is transformed into the white manaless husk of what it once was. Ulamog is emblematic of plague, the blind bonds between parasite and host, and overabundance. Ulamog is creation and destruction wrapped together in unholy harmony.
The Ulamog brood lineage is characterized by dense masses of suckerless tentacles, multiple withered arms bifurcated at the elbow, and most unsettling, eyeless bony plates in inhuman but vaguely facial forms. The ravenous and brutish Eldrazi of the Ulamog lineage lurch and shudder over the ground, adept at spreading disease and draining from the psyches as well as the life energy of their victims.
