Mysidia(ミシディアこく">ミシディア国,Mishidia Koku?, lit. "Country of Mysidia") is a town in Final Fantasy IV and Final Fantasy IV: The After Years. It was founded by the Sage Minwu, who drifted ashore 500 years before the events of Final Fantasy IV. Practicing magic was initially a benevolent hobby accessible to everybody, but people eventually became corrupted by power and competition.
Minwu was enraged by this and sealed away magic, and the Old Age of Magic came to an end. He later restored magic but made it so that only certain persons could use it, and this became the start of the New Age of Magic. Mysidia is inhabited by wizards, and is ruled by an Elder. It is the hometown of Palom and Porom, and is one end of the Devil's Road, which connects Baron and Mysidia. The Tower of Prayers is located in Mysidia, and is where the Elder prays for those he cares about.
Cecil visits the Elder and explains he was banished from Baron and is fighting Golbez. The Elder says Cecil cannot defeat him using his Dark Sword, and that he must travel to Mount Ordeals and become a Paladin. The Elder sends Palom and Porom to help and keep an eye on him.
Cecil returns as Paladin wielding the Mythgraven Blade. The Elder reveals the sword is passed down in the Mysidian Legend and says Cecil is the Chosen One, and must defeat Golbez. He opens the Devil's Road so Cecil can get to Baron.
Cecil returns after Golbez has gathered all the Crystals. He is invited to pray with the Elder in the Tower of Prayers, and their prayers are answered with the Lunar Whale, the airship that can travel to the Red Moon. After the Giant of Babil is destroyed, the Elder, Palom, Porom, Yang, Edward, Cid, King Giott, Luca, and others pray for Cecil to defeat Zemus on the moon.
Ceodore Harvey and the Hooded Man reach Mysidia on their way to Baron where the Hooded Man suggests to go to the Devil's Road, a secret passage that leads to Baron. They enter the Prayer's Hall where they meet Porom and ask her permission to pass the Devil's Road. Porom sends a White Mage and a Black Mage to guide them.
In Edge's Tale, Edge sends Tsukinowa to spy on Mysidia and gather information as a magic trainee named "Lapin". Tsukinowa spies on Porom and follows her to Mt. Ordeals, returning to Edge when he sees the Tower of Babil glowing ominously.
In The Crystals, Rydia, Luca, Edge and the Man in Black come to Mysidia and engage Ramuh to rescue Porom and the village from his wrath.
The building is the first structure on the east side of the town. The pub is found in the first floor and the town inn on the second. The black mage on the counter will poison Cecil's drink, and the dancing girl is an old mage in disguise, who will transform Cecil into a pig and kick him out of the pub. This will happen even after Cecil becomes a paladin.
Hall of Prayer
The Hall of Prayer is the building farthest north of the town. When Cecil enters the hall, the Elder will tell him to become a paladin on Mount Ordeals, and sends Palom and Porom with Cecil as spies. After Cecil returns a paladin with Tellah, the Elder will warn the old mage about Meteor's destructive power.
It is just upstairs the Hall of Prayer. The crystal room is first shown in the cutscene when Cecil raids Mysidia. If the player visits it, the dais will be empty. Upstairs the crystal chamber leads to the Tower of Prayers.
Tower of Prayers
The Tower of Prayers is accessible from the door farthest north in the crystal chamber. If the player visits the elder before Mount Ordeals, the elder and mages will say that they are praying for him and the whole world. After Palom and Porom's sacrifice, the elder will give the player augments. After the events of the Sealed Cave, the player must head here, where the elder is praying along with some mages for the Lunar Whale to appear. After the events of the Giant of Babil, the whole party is present in the tower, and will offer Cecil's group words of encouragement. When they sense that Cecil and others are in danger, they pray harder.
Mysidia's theme, "Mystic Mysidia", features some peculiar elements not found in many town themes throughout the series. Its fast tempo and the inclusion of a cuckoo bird's chirp within the rhythmic section are but a few of these. A rearranged version of the theme was included in Final Fantasy IV: Celtic Moon album.
