Zurvan, the Demon is a primal from Final Fantasy XIV, introduced in patch 3.5, "The Far Edge of Fate". Alongside Sephirot and Sophia, it is based on a member of the Warring Triad from Final Fantasy VI.
Worshiped by a Meracydian race of centaur-like beings, this eikon manifested upon the physical plane as an embodiment of eternal victory. And yet, despite his godlike might, Zurvan was captured. He has languished in his Allagan-made prison now for five thousand years, his primal desire for justice swelling in magnitude with each passing millennium...Official description
When Sophia is defeated her thralls free Zurvan's thralls and begin attempting to rouse their master at full power. The Scions and the VIth Legion cooperate to stop the thralls' ambitions by destroying the four towers that feed Zurvan aether. With three towers destroyed, Unukalhai struggles to destroy his, and Regula assists him only to be blindsided by a swing of an awakened Zurvan. The blow is blocked, his sword breaks, and Regula suffers a fatal wound. With his final breath he urges the Warrior of Light to defeat Zurvan. After a tactical retreat the Warrior of Light and a party of echo-blessed adventurers defeat Zurvan.
Defeating Zurvan in the extreme version grants the achievements "Zurvan Safari" and "Mightier than the Demon" if you complete it with a party of 8 blue mages while synced, and the echo turned off for the latter.
Creation and development
Zurvan, Sephirot and Sophia are based on the Warring Triad from Final Fantasy VI. Zurvan is inspired by the Demon, his name is taken from the working name Demon had. While there is a monster called Zurvan in the remakes of Final Fantasy VI, the Zurvan in Final Fantasy XIV is based on the Warring Triad original member.
Like with Sephirot and Sophia, a rearranged version of "Battle to the Death" from Final Fantasy VI, called "Battle to the Death - Heavensward," plays in the first phase of the battle against Zurvan. Two new tracks called "Penultimania" and "Infinity" play during Zurvan's second phase, unique to him. Unlike "Fiend" and "Equilibrium," there are two tracks in the same phase, with "Infinity" playing after Zurvan uses his signature attack, Ahura Mazda.
Zurvanism, Zurvan is the god of infinite time (and space) and is Aka Manah ("one", "alone") deity of matter.In
Much like the Final Fantasy VI character, Zurvan's deific title of Demon possesses a certain level of translation ambiguity; more information can be found on the relevant page.
