Out of the fourteen purple marks for SS Dungeon rifts that Taranis had seen on the world map through Vivi, there were three that glowed more brightly than the others. They were located in Tokyo of Japan, Heidelberg of Germany, and Kolkata of India.
According to Celestia, there were also only three beings in Rukadvatta that were as powerful as she was.
Taranis had requested Ume to take care of the one in Tokyo, while Celestia and Nymeria were supposed to handle the one in Heidelberg. As for Taranis himself, he had already arrived in Kolkata. Once they were done with their respective battles, they were to immediately teleport to the other locations where SS rifts were supposed to appear.
