Negerai
One day, almost by chance, Avlis received a visitor that would shape its history forever to come. The Negeri, an evil entity from the depths of the Abyss, flew into the crystal sphere on a spelljamming vessel with nine human prisoners. Now this Negerai was extremely intelligent and twisted, like most specimens of his kind, and oddly enough, this individual had a great love for humanoid (especially human) psychology. His greatest fascination was the study of good, evil, and neutrality in humans. Even though he was a vile creature in every way, he still had interest in the mechanism that made people behave in alignment with a certain philosophy. He felt that if he could study these attitudes more in depth, he would be more apt at controlling large numbers of the creatures to do his bidding.
