The Battle of the House of Hades was a major battle during the Second Giant War. It was the front out of Tartarus of the Battle for Control over the Doors of Death.
History[]
During the battle, praetor Jason Grace, son of Jupiter, led his demigod brethren of the Argo II to attack the armies of the giants led by the resurrected Pasiphae and the giant Clytius. During the battle, Nico di Angelo summoned an army of undead Roman legionnaires using the Sceptre of Diocletian. Jason was unable to control them due to him not being fully Roman (he was siding with the Greeks) and thus voluntarily gave up his rank and promoted Frank Zhang, centurion of the Fifth Cohort in the Twelfth Legion, to praetor. Frank was able to command the ghosts and led his allies to victory in the battle.
Meanwhile, Hazel Levesque and Leo Valdez travelled alone, further into the House of Hades, to defeat Pasiphae. With the help of Hecate, Hazel gained control of the Mist and learned to use magic. She defeated Pasiphae and with the help of Leo, saved Percy Jackson and Annabeth Chase from Tartarus. The seven then killed Clytius after this before leaving for the surface.
