Kael Lughson, a modern-day college student and martial arts prodigy, never expected his museum visit to turn into a one-way ticket to a war-torn, mythical Ireland. Thrust into the realm of Ériu, Kael is imbued with the divine power of Lugh, the Many-Skilled God, and wields the legendary Gáe Bolg—a spear that never misses and curses its foes with thorny doom. Marked by prophecy as the spear-bearer destined to unify or destroy the land, Kael must navigate a world of gods, monsters, and ancient clans, all while battling the Fomorians, a race of monstrous invaders led by the sinister Balor.
But Kael isn’t alone. Guided by Morrígan, the seductive war goddess, and trained by Scáthach, the stoic warrior-queen, he attracts a growing harem of mythical heroines—each with their own powers, pasts, and affections. From the wise Sidhe queen Ériu to the fiery archer Gráinne, Kael’s charm and strength draw them into his quest, forging bonds of love and loyalty amidst the chaos of war. Yet, as his power grows, so does the risk of the Ríastrad, a berserk state that could consume him.
