Mal-Kalen is a spirit, roaming the Ulcaster school ruins in Unfinished Business for the classic Baldur's Gate and the Enhanced Edition. He is encountered in the northeastern part of the ruins (go as far as you can after making the first "left turn" from the stairs). He resists Know Alignment and Detect Evil. Treasure: Mal-Kalen carries no treasure of any kind and gives up only 2000 experience points (given the difficulty of the fight, it seems lacking.)
