After a short trek the group of explorers found a group of angels who were able to answer quite a few of their questions. They found they were on the plane of Ysgard and what was worse is they were in an alternate reality where the prime material plane was called Abier.
Since they had no where else to go, they just started to explore. Soon they found something very peculiar, a temple with statues of unknown gods, but inside it was a temple to Mystra.
After solving a number of puzzles and dealing with a demon in disguise, they found a very interesting tome.
They had to figure out where to go to next. In an unknown world, with no allies, and little in the way of power they had to pick the most friendly of places. They decided upon Celestia.
