Glory found an animus-touched tunnel in the Rainforest Kingdom that leads to the Kingdom of Sand. She described the desert as "always hot and clear with no rainy days". The tunnel is hidden by sand right outside of Burn's Stronghold, and the wind blows sand to cover it up every day, which is why Burn had not discovered the tunnel entrance. The NightWings had wanted the tunnel there so that when Blister became queen, she could help them seize the Rainforest.
