Rune Seeker: A Progression Fantasy litRPG (Series Complete)

In a world where sunlight fuels magic through living tattoos, Hiral is the Everfail—the only person on the flying island of Fallen Reach unable to channel his immense inner power. He trains harder than any warrior and studies longer than any scholar, yet all his effort yields nothing. Until a moment of danger unlocks his first achievement: Access a Dungeon to receive a Class-Specific Reward. It’s his one shot at real power. But all dungeons lie in the deadly wilderness below the floating islands—a realm of secrets and monsters no one has survived. New powers await, but failure means far worse than death.
