In a universe far beyond our own, where light itself is alive, the cosmic force known as the Luminance gathers a ragtag band of heroes—the NaKnights. Each hailing from the worlds across the Nanoverse, they're sworn to stand against the rise of Kah Umbra, a once-revered spiritual leader now twisted by darkness and obsessed with bringing about the age of “Oblivion.” Leaderless & outnumbered, the NaKnights must recover the lost totems of the Luminance and fight to preserve the light in a universe on the brink of falling into eternal darkness.
