Wings Back Home

Cielarmon, a place of peace and diversity. The Ravens were the peacekeepers of the lands, teaching the other nations how to defend themselves and hunt. Each came about these in their own variations, though stemming from the Raven's guidance. No one knew their home, it was seeming nonexistent.
Everything was fine until the Eagles found a Unalian Crystal, one that could hold the power of a thousand flames and could tear the veil between worlds. With the newfound power, the Eagles took off, lustful for blood. They attacked the other nations, attacking the smaller villages first. The Ravens formed together to protect everyone from the tyranny of the Eagles, though out of the blue, the Ravens disappeared. Rumor has it, the Eagles found their hideaway and slaughtered every last Raven there, or that the Ravens caught cold feet and fled from the fight. Fear swallowed the nations.
Now with the Ravens gone, it was only themselves that could defend what they had built up for generations. The Falcons, being in close relations with the Ravens, stood up for the task of supplying the refugees that had come for their care. It was a fierce battle, the nations were always on high alert in fear of the Eagles. Despite the efforts of the unity, the Falcons were struck down by the Unalian Crystal, the genocide of the nation spread fear and panic throughout Cielarmon. The Unalian Crystal was only used as the Eagle's final blow, the tearing of the veil between worlds became uncommon but still likely.
Within a few years, the Eagles had trampled over Cielarmon, leaving it in a deep tyranny. The nations that survived are now in hopes of not being hurt by their new rulers. Rebellions would be swiftly struck down, as any leak would lead to genocide. The buzz about what to do now is a mere spark, quickly extinguished by the iron fist ruling them.
Though... what happened to the Ravens? What happened to the three that had simply vanished?
