Exostrider

A colossal mech of alien origin, now dormant in the Roya Frostlands. Startorch Academy was founded to train Synchronists capable of establishing Augmented Resonance with it.
In the Roya's Trine Myth, it is revered as Baldur, the earthly incarnation of the sun deity Sol. Legend claims it once held up the earth's collapsing crust with its greatsword, saving the Roya from annihilation. Predictions foretell it will awaken from its slumber to confront the ruinous Hvedrungr in a final, apocalyptic battle.
