In 1521, this canyon was the site of three week battle between a horde of jara, the Pig Tramplers and the chaos army of Neeth-Theen. Beasts of chaos rose from bubbling pools, attacking without fear or quarter. Ushgergoon, a mighty slaad leader, waded into the invader's ranks, dropping three and four with every blow. After this battle, this area came to be known as Bone Hoof Canyon.
