A Hero's Blood{A LitRPG Apocalypse}

When the System arrived, Dublin Bay turned black as ink. Sean O'Brien watched from the ramparts of Dublin Castle as dark waves crashed against the shore, each one bringing something ancient and terrible closer to land. As a broke history student who'd spent his last euros on a castle tour, he didn't expect to become its final inhabitant. But when everyone else fled inland, his newly awakened bloodline pulled him to stay.

[Bloodline Detected: Heir of Fionn Mac Cumhaill]
[Legacy Class Available: Fenian Hunter]
[Warning: The Sea Holds Ancient Enemies]

Dublin Castle became his fortress - a massive stone sentinel overlooking the corrupted bay. The System's changes made the medieval castle more defensible than ever, with walls that seemed to hum with old magic. Sean quickly learned why he needed those walls.

They came from the sea first - massive shapes rising from the depths. The Fomorians, ancient enemies of Ireland, had been waiting beneath the waves for millennia. The System's arrival weakened the magical barriers that had kept them contained. Now they surged forth from their underwater kingdoms, led by their one-eyed king Balor, whose gaze could turn armies to stone.

Can Sean create the new Fianna in time to stop Ireland's old enemies from taking over the world?
