In the early days of the North, Maulaugadorn was a great warrior who created for himself a kingdom in these lands, worshiping Tempus.
One day, however, his sister Alandalorne was caught by a strange illness. Maulaugadorn invoked his god and Tempus explained that his sister was a sorcerer and her powers were starting to reveal. Thus Maulaugadorn wanted to learn magic, in his mind a new kind of weapon. At last Mystra decided to reveal to him explaining how to become a wizard.
In time, he become a great wizard, eventually creating the malaugrym.
He was the first human exploring the Plane of Shadow and gained from this great mastery over shadow magic. At the same he become an inhuman abomination (a proto-malaugrym).
