For many years, Manxious had slowly been expanding the empire of Lusturum. During this time, he found out that this plane is incredibly unstable. It was right when he was about to enter the war, Mystra spoke to him.
This world is highly unstable, but over time, this plane could prove invaluable to the multiverse. For this to happen, the now native people, would have to slowly adapt to this world.

He had a son, which he would call Kirian Aaron Valthorpe. He would be the first Deviner and bring stability to this realm.
