FlyKnight follows a squire of the order of the Flyknights — a rank earned by all who serve the winged warriors of the realm. The order has been assembled to confront the witch Lunamoth, whose curse has spread across the land and stolen the wings of every creature she has touched, leaving the realm grounded and vulnerable.
The squire's unit is ambushed and scattered before reaching her. Alone in a swamp village, the squire makes a pledge to see the mission through regardless, whether by fighting solo or gathering other summoned fighters who answer the call along the way. The journey toward Lunamoth's lair is the path to Knighthood — or the end of both the quest and the squire.
