Unbound Mage

Aaro was stuck in a dead-end life until a divine beauty appeared with a deal: magical powers, a new world, and a chance to matter. One decision later, he's wielding magic that defies every limit he's ever known in a world more vibrant and real than earth ever was. But power without purpose is meaningless, and in this world just surviving isn’t easy. As he serves the goddess Nyxaria, just protecting her followers will take more than learning new spells in a realm where war looms and ancient powers stir, because being chosen by a goddess comes with a price. Good thing Aaro's ready to pay it.

Aaro defended the kingdom against the Horde, but now the peace between the pantheons shattered. Enemies from below prepare to strike the kingdoms and temples across the surface. But defending his land won't be enough. The enemy cities lie hidden beneath the earth, and finding them means venturing into darkness where his magic and his family will face their greatest test.
