ChieftainKrag'jin was a forest troll leader of the Shadowglen trolls. Krag'jin stationed his people along the River Arevass in the Silverpine Forest, where they had built several dams and set up homes up the river.[1] During Malfurion and Illidan's joint attempt to save Tyrande Whisperwind and the Sentinels accompanying her, Illidan and his naga slew the Shadowglen Trolls in order to make a faster route to the Undead Scourge base — which was besieging Tyrande's group. Krag'jin and other forest trolls died defending their dams.[1]
