Upon Cecil and Kain's arrival at Mist, the package opened by itself, and Bombs were released into the village, setting it on fire and killing most of the highly-trained Summoners. While the village burned to the ground, the two found Rydia clutching her mother's corpse in shock. Overhearing how they slew the Mist Dragon, Rydia correctly accused Cecil and Kain of murdering her mother. Kain then half-heartedly suggested killing her as he had surmised that the King of Baron must have wanted the Summoners dead.
Cecil urges his friend to reconsider and the two decide to fight back against Baron, no matter the cost. Concerned for the girl's safety, Cecil offered to take Rydia with them, but she vehemently refused. When the soldiers pressed her she summoned forth Titan, who caused a massive earthquake that separated Cecil and Kain and caused a massive landslide that would block off the Mist Valley.
Mist is the only town in the game that does not have an Item shop.
With the bypass event glitch it is possible to avoid visiting Mist when Cecil and Kain are meant to deliver a package there at the beginning of the game. By skipping Mist Kain does not leave the party and Cecil never meets Rydia. If the player then enters Mist from the "wrong side" the event where Mist is burned down doesn't trigger, and the player can visit Mist's weapon shop earlier than intended. The whole game cannot be played without triggering the scene where Mist burns, however, as Tellah will never join the party at the Underground Waterway unless the scene at Mist has been triggered, which freezes the game at the set battle where Tellah is meant to battle Edward.
