Idraiginn is the elite unit on Setera that the player joins at the start of Chrono Odyssey. It exists to fight the Void directly, to protect the survivors of the eleven planets the Void has already consumed, and to keep Setera from becoming the twelfth. Idraiginn is the player's organizational home: every meaningful quest in the early game routes through it in some form.
Purpose
Idraiginn was founded to deal with a single problem: Setera is the last surviving world out of the twelve Chronos created, and the Void that destroyed the other eleven is still active. Conventional armies, even Setera's well-organized Frontier, are not equipped to confront Void apostles, corrupted Sentinels, and Void Nexus incursions on their own. Idraiginn was assembled to fill that gap with a small force of specialists trained for the unusual demands of fighting Void-tainted enemies.
Membership
Membership is selective. Players take the role of one of Idraiginn's Vanguards, elite operators who carry a Chronotector and who can act on Idraiginn's behalf without waiting for political clearance. Each Vanguard is expected to operate independently when the situation calls for it. In practice this is why the player is the one tackling Chrono Gates, investigating Void Nexus outbreaks, and chasing down corrupted World Movers who have crossed lines that Setera's existing forces cannot or will not cross.
Relationship With Other Factions
Idraiginn is its own organization. It is not the Chronos Order, which is the religious institution organized around Chronos's worship, and it is not the Frontier, which is Setera's standing military. Both of those institutions cooperate with Idraiginn on the Void problem from their respective sides: the Order provides public legitimacy and morale through the Saintess's prophecies, and the Frontier provides the broader military presence that holds territory while Idraiginn focuses on Void-specific threats. Idraiginn's relationship with the Order's Knights Templar is cordial, with overlapping mission sets but separate chains of command.
With World Movers the relationship is more complicated. World Movers are refugees from worlds the Void destroyed, and many of them carry Void contamination of their own. Idraiginn treats individual World Movers as potential allies first and potential threats second, but the unit reserves the right to act against any World Mover or Outcast community that becomes hostile. The Deathless cult, which actively embraces Void contamination, is treated as an outright adversary.
Story Role
Idraiginn anchors Chrono Odyssey's story and narrative. The player begins the game as a Vanguard, witnesses Setera's destruction at the Void's hands during the prologue, and is sent one year into the past by a Sentinel to prevent it. The unit's name, internal hierarchy, and broader public reputation are introduced in the early hours of the game and remain present throughout the main storyline.
