Brilliant, curious, and always in control, Jace is a master of mental magic: spells of illusion, deception, and mind reading. His powers allow him to manipulate enemy mages by countering their magic or using their spells against them. An adept analyst, he has an optimized plan (and a backup plan) for every situation.
Growing up as a magical prodigy on his home plane, Jace Beleren sought out the training of the mysterious sphinx Alhammarret. Under the sphinx's training, Jace learned to control his abilities. However, when Jace discovered that Alhammarret had been using him for political manipulations, he confronted his master in a fierce mental battle. The battle badly damaged Jace's memories and caused him excruciating pain. This distress ignited his Planeswalker spark, tearing him away from his home plane.
