Krallen were huge, up to 40 meters tall at the shoulder and up to 65 meters long. Krallen originally hailed from the plains and swamps of Yavia, and were apex predators in that region. Krallen had flat faces with massive saber teeth. Although young Krallen only had four limbs, adult Krallen possessed an extra pair of grasping hands on their shoulders, which aided in subduing large prey. The Yavian warlords took advantage of this feature to aid in looting enemy bases.
