In a faraway realm known to be Alfheim, was once ruled by elves with wings. Now it has ended and the vast land contains of that of nine elven tribes, spanning from one direction to the other, North, to South. Some tribes even included or claimed stranded islands if their land is marked near the sea.
Life was flourishing around the grand world tree, in the very center, surrounded by vast forests and streams around it, many believe that it stretches beyond the clouds, since no one has ever reached the top of the branches, before.
Living in a small home, outside a decent-sized village called Elysia, owned by the Pasmeda Tribe or the light elven tribe. Syvis Leon, a black-haired young elf, has never felt free, in his lifetime, after he left his parent's house.
Up in the branches, beyond the clouds a young ashen-haired elf, with two shimmering crystal clear wings. Princess Patri Leoxina has always imagined a life below the clouds but despite her reasons and constant PowerPoint. Her father, the current King, won't allow her to explore the vast land, underneath clouds. Even her over-protective older brother, who won't hang out with her anymore, is starting to believe their father's words that her dreams are dangerous.
With many dangers and the constant rumours of the ordinary elves, she begins to launched herself into the dangers below the tree after she fell from her home during a fierce storm.
TR;DR, the ideas of the nine tribes taken from Sword Art Online's Alfheim Arc, and later twisted to fit my imaginations on what if there is an actual world based off the virtual world Alfheim Online. *cackle*
