Taking the Medieval AU further…
Imagine Amon, the masked bandit king, leading his crew of not-so-merry men to purge all those of noble bloodlines—regardless of the social status these sections may hold.
Picture Unalaq, the sinister sorcerer who seeks to summon the demon Vaatu and plunge all kingdoms into eternal darkness.
Consider Zaheer the Imprisoned Monk, who bears the crest of the Red Lotus and leads three of the world’s deadliest assassins on a quest to destroy Korra and the rulers of nations.
And finally, Kuvira, the champion of Lady Suyin and the paramour of the Lady’s eldest son, who rides out and takes up the banner to unite her shattered kingdom—but soon proves to be an unstoppable tyrant.
