Immortal Celtic Warrior

Aiden McGuiness is an Irish warrior who loses his family, flees to sea, and spends decades becoming a skilled fighter. After being mortally wounded while protecting a child, he is saved by the goddess Bridget, who grants him immortality and makes him her champion. Aiden tries to build a peaceful life with Derry, but his new calling forces him to protect the innocent, rescue captives, and face the painful cost of living forever, alone.
