Keiran: The Eternal Mage

Keiran of the Night Vale has cheated death for two millennia, but his ancient body is finally failing. Using his prodigious talents, he reincarnates—only to awaken in a desolate wasteland where mana has become desperately scarce. Starting over in a young body with centuries of knowledge, he must rebuild his power in a world far harsher than the one he left behind. A rich progression fantasy following an overpowered mage humbled by circumstance, blending deep magic systems with a compelling journey from the ground up.
