The Final World Battle

The Final Battle, also known in in Norse mythology as Ragnarök, is a series of events that end with the deaths of the Norse Gods and the end of the world. When the world ends, it will be reborn again.

A God by the name of Odin, has been preparing for this Battle by having the species of the Valkyries search for the souls of the most worthiest warriors who'd previously died in battle. The Valkyries are then tasked with taking them back to the land of Valhalla, to train these warrior souls to fight in the last battle between Good and Evil.

2003
During the year 2003, three Valhalla Warriors went through a portal whilst chasing the Charmed Ones and were teleported to the city of San Francisco. The amount of evil that the city contained confused the warriors into thinking the final battle had begun, and they killed several innocent people. The Valkyries arrived in San Francisco to retrieve the warriors, and had to fight them until they were finally able to convince the warriors that the final battle hadn't started yet. After opening a portal back to Valhalla, the Valkyries and the warriors returned to Valhalla safely, leaving the world intact the final battle yet to happen.
