The Chosen and the Saviour
16 parts Ongoing Harry Potter and his friends must redo their 7th year at Hogwarts because of the Battle of Hogwarts. Percy Jackson and his friends are enjoying themselves at Camp Half Blood, 2 months after the Giant War. However, all of this changes when Chiron assembled the Seven and some more demigods to embark on a quest.
The Giants have been reawakened and brought back by an unknown force and have learnt magic which the wizards possess. The Giants have gone back in time to the same year Harry Potter is repeating his Seventh Year, in 1998 to bring back the Dark Lord. It is the demigod's mission to be students at Hogwarts, befriend the Chosen Wizards and defeat the Giants from bringing back the Dark Lord. Even worse, the Demigods can't use their godly powers within certain magical borders, including Hogwarts.
Will the Chosen One and the Saviour of Olympus prevail?
