The battle rages through the Timestream, and your might holds fast against the Tyrant's onslaught. The Tyrant feels his energy draining away, and your assaults come closer and closer to finishing him once and for all.
But the Tyrant holds on until the journey is complete, and in the fire that bore the universe into being, he channels that energy into one last strike that destroys you. And so the Tyrant, though greatly weakened by the fight, goes on to begin his plans of conquest.
Meanwhile, your essence, your steadfast determination and rejection of domination, refuse to die. It spreads out across creation, and will be the key to humanity's survival in ages to come, After the Collapse.
