Oath with the Silver Mane

The floating continent Asteria, suspended high above the sky, has remained in peace for thousands of years, isolated from the world below. But when shadow beasts rising from the abyss begin to invade this sacred realm, the Valkyrie Wing—Asteria’s most powerful order of guardians—awakens from its long slumber.

Elena, the commander of the order, mounts the legendary ancient divine beast known as the Black Tempest and stands alone against thousands of shadow creatures to defend the collapsing boundary of the heavens. Each time her spear flashes, a waterfall of radiant light pours through the clouds, and the people on the ground look up in prayer, believing that they have not been forsaken by the gods.
