Brothers in Arms

Percy is the son of Poseidon.
Jason is the son of Zeus.
Nico is the son of Hades.

These are the legendary warriors of old. Born from the bloody battles of war, they have a bond stronger than any other. Separated they are powerful, but together they are unstoppable. These are the deadly and powerful demigod son's of the eldest son's of Kronos. They have fought in both mortal and immortal wars. The divine shiver at their names, monsters run at the sight of these three brothers, and their enemies die by the swiftness of their blades. Can these legendary warriors face down the endless hordes that have been called upon from Tartarus himself? Or will they fail to defeat the most powerful child of Chaos?
