The ormyrr were a race of roughly humanoid reptilian creatures who lived on the planet of Krenindala prior to the War of the Worldreaver. Though much more brutal and possessed of greater size and strength, the ormyrr bear a passing resemblance to the Xoran race, due to the origin of Xorans from forcible cross-breeding between the ormyrr and Elara.

Due to the hostility of the brief contact between Krenindala and Achaea, little is known of the origins, history, or culture of the ormyrr. Their society was organized into regimented castes, with the priest caste at the top. The priests served the great worm-like Dala'myrr, who in turn served Bal'met, the mysterious god of the ormyrr. The ormyrr believed that Bal'met dwelled within the core of Krenindala, and that he chose the most devoted priests to undergo the harrowing metamorphosis into Dala'myrr.

Following the first contact with Krenindala, the ormyrr reacted with immediate suspicion to the Sapient presence. On Krenindala, only the ormyrr were worthy of regard; all other races were slave races, and to see non-ormyrr walking around freely was a sure sign of slave rebellion. The ormyrr worked to kill all Sapients on Krenindala, eventually discovering the portal and invading Sapience at the behest of their Dala'myrr masters.

During the War of the Worldreaver, the ormyrr were the nigh-inexhaustible foot soldiers of Bal'met, willingly throwing themselves in vast numbers against fortifications and foes alike. The sheer size of their forces and the deadliness of their warriors made them a formidable threat, which was only defeated at great loss of life or, in the final battle, with the assistance of semi-divine powers.

Following the defeat of Bal'met, the remaining ormyrr on Nishnatoba were slaughtered. Krenindala was scoured clean by the death of Hermes, but since the portal was destroyed, it is unclear whether any life survived on Krenindala. As a result, it is unknown if any ormyrr survived, either on their home planet or on Sapience. If so, they would be terribly alone, the last of their kind, bereft of both priests and God.
