Known only as Zahak, this mysterious warrior exudes an aura of mystery around him, as very little about his past is known, even to members of the Enclave. While his eyes are almost always covered by his sunglasses, it's clear that he's always sizing up his surroundings and his allies. While he can and will come up with comprehensive battle plans, he is also quick to improvise if necessary. Zahak seems to be very skilled at occupying an enemy's attention, and drawing it away from wounded allies.
However, during his mission in the Soulless Lands, he seemed to let a little bloodlust out while he blasted the invading army with his Thunderbolts and Thunderclap. Usually stoic, this could just be a one time thing, or maybe he let's loose when he's facing unlikely odds. On the same mission, he advised his ally Danarei to search for anyone among the army with different uniforms, on horseback, or towards the rear, suggesting they might be command personnel who should be targeted first to sow chaos amongst enemy forces. This hints at prior military experience or knowledge, including his remarks about an obscure last stand by a few against a large army.
During his mission into The Simulation, Zahak channeled enough arcane energy to enhance the effects of Storm Brewing for the first time to save Ardis from hitting the ground at terminal velocity. By focusing on only them, he enhanced the power of the summoned gust of wind to slow her fall enough for her to land safely. This new ability perk of his, due to the focusing on a smaller area or group, has been dubbed "Eye of the Storm"
He seems to wear an unusual symbol around his neck, which he often tucks inside his armor for safe-keeping on missions. It's unknown exactly where he hails from in Manifold, or even if he's from any known location at all.
