Accidental Champion

Xavier Collins was sitting in class when the System integrated Earth into the Greater Universe, where countless vast kingdoms, empires, and collectives battle for domination. He didn't know what choosing to be a Champion would entail. He just liked the sound of it. But when he's teleported to the aptly-named Tower of Champions, he must face challenges against those who have known about the System since birth.

After an unstoppable ascent through the Tower of Champions, Xavier has cemented his place as the True Progenitor of Earth by attaining the top leaderboard records on floor after floor. Now he finds himself on the fifth floor, defending Queen Alastea and her castle from the infinite waves of the Endless Horde. They say the Endless Horde can't be stopped—but Xavier has always been bad at listening.

Xavier’s rise through the Tower of Champions has been meteoric, and on his return to Earth, he hits the ground running, clearing dungeons, claiming titles, and gaining mastery over forces that should be beyond his control. But with Earth’s exposure to inter-planetary warfare, threats from the Bellaran Confederation, Tri-World Imperial Army, and vengeful foes threaten to tear everything he’s fought for apart. With his companions by his side and the weight of the world on his shoulders, Xavier must protect his world at all costs.
