This axe, fashioned of the finest darksteel, bears the inlay of a majestic golden wave, modeled after the Kingdom of Ephramad's royal insignia. Its name allegedly derives from an ancient source and is symbolic of the inexplicable powers of influence the weapon seems to exert over others. It is said that the legendary Admiral Veydal forged the axe in an attempt to harness the power of the mighty Leviathan.
In Phoenician mythology, the god Baal Hadad had had two weapons made, Yagrush ("chaser") and Aymur ("driver"), to combat the tyrannical sea god Yam-Nahar. He struck Yam on the chest with Yagrush to no avail. Then he struck him on the forehead with Aymur and fell Yam to the earth. After Yam's defeat, Baal had a palace built for himself. The story parallels the conflict between Marduk and Tiamat in Mesopotamian myths.
If you compare the Weapon Skill animations of Yagrush and Aymur, you will notice that they are similar in motion, showing that there is a link between them.
