During the war between the Alliance and Horde, Leza, including Dezco and other tauren from the Dawnchaser tribe, dreamed of a vale. Hoping to find it, Dezco led a group of Dawnchaser tauren set out from their enclave within the sunny plains of Mulgore on a journey to find Pandaria, and the Vale deep within the continent. During the voyage, three of their four vessels were destroyed by the violent storms, which caused the death of several friends from the expedition while most of the survivors were saved. Only one vessel made landfall in the coastal jungles of Pandaria.
Once they landed, they set up Thunder Cleft as their base to be used in the search for the Vale and for Leza to have her babies. After Leza gave birth and passed away peacefully, the tribe continued on in their search until they finally found the Vale of Eternal Blossoms. They, along with some Horde that followed them, moved into the vale and settled at the Shrine of Two Moons.
