To find Ekeyakke in the "Ekeyakee" quest given by Segra Darkthorn in the CrossRoads, go northeast to Grol'dom farm. Head to the east side of the mountain, where you will find the bones of a Giant Kodo near a tree. Stand next to the head and blow the horn. Ekeyakee should appear standing next to the tail and is a level 16 White Lion. You will need to tame him. If you kill him, then you will not be able to repeat the quest.
