Grid Jihad

It tells the story of how far back in ancient times, in the Elven Age between the First Era and the Third Era, several "Children of the Wind" were not afraid of hardships and dangers, and joined forces with the tree elves and leaf elves to fight against the dark "Undead King" Merlinson. Finally, with the help of the high elves, they saved the continent of Grid that had fallen into the rule of the Dark Empire.
