Cain gathered up the other Avatars as soon as Moana got the message from her clone and got ready to head to the place known as End of the World to meet the Librarian.
They had been on this quest for a rather long time now, and it was time to get it finished. The reward should also give him something very good, and he was hoping that it would let him advance himself to Spirit Awakened.
At the moment, he had everything that he needed except for a Spirit Rank item, and he hadn't seen one of them anywhere on the planet up to now, so the quest might be his best and possibly only chance to actually acquire such a powerful item.
The real mystery was what the other Avatars had to do with anything though. Sure, they were fun to have around, but so far they hadn't had anything to do with the search for the Librarian that Cain's summons couldn't do as well or better.
