Slumbering Exostrider

During the second Lament recorded in Lahai-Roi, the Exostrider, a colossal mech from an unknown civilization, emerged through the Stridergate. It fought a fierce battle against the Threnodian to seal the catastrophe from the other side, a clash that shattered the very bedrock of the frostlands.
As the Roya faced annihilation, the Exostrider channeled its remaining power and drove the greatsword deep into the earth to brace the collapsing land. Its Reactor Drive transformed into a subterranean sun, casting warmth into the depths. Its scattered fragments reassembled into the Exoswarm that mimic the local lifeforms, guiding the Roya toward a new homeland. Since then, the Exostrider fell dormant upon the surface, awaiting the day of its awakening.
