Cruniac was the commanding officer of The Legion in the events leading up to the war against Soulblighter.

Cruniac was noted for having more interest in politcal manouvers then military ones but he has a great level of tatical skill, as demonstrated when he enlisted the help of the dwarven pathfinder, Jari, in capturing Kildear castle.

He also seemed to have experience in dealing with magic when he broke a mind control enchantment that controlled a human guard.

He was mortally wounded by Soulblighter during The Legion's rereat from Kildear Castle, but not before warning The Legion of the fallen lord.
