Old cranky gnome with an additude and fireballs.
Jaren grew up in the era before the spellplague. He watched as clouds of spellplague ripped his farmstead into nothingness and left him forever scarred. Wondering around the northwest for decades he eventually learned to draw power from his spellscar as a source of magic. The chaotic nature however caused his powers and ability to be somewhat unpredictable for years until they stabilized just recently in the destroyed town of Tunia.
Jaren has been around a lot longer than the other Harpers, being one of the few individuals remaining that remembers when the weave was intact. Being that old makes him grumpy with a tendency to harness arcane energies to burn away anything that pisses him off.
