DN the first managed to get hold of the chord and killed GT and PK while casting the spell to change reality. GT and PK woke up in and found out that reality had been changed. Only GT and PK were able to remember what happened in the real world. In the new world that DN created, the immortals never existed and everything was different. Things were bad for the immortals but for the villains, the world was good. It's up to GT and PK to find everyone who was in the immortals team, find the chord and put things back to the way there supposed to be.
