Mognet is a service run by regular moogles and is exclusive to the remake versions. In the DS version, the moogles will deliver letters to either in-game characters, or to other players over Wi-Fi (though now discontinued). In the iOS, PSP and PC versions, the letters unlock at certain points over the course of the story and players have to read the new piece of mail at a moogle found in towns before getting the next one. It is through Mognet that the player can unlock the secret dungeon and the secret job class.
Mognet is led by Artemicion. However, recently, the delivery of letters has slowed down, and the moogles have to rely on Zidane to help. The player's party can investigate the mystery of Mognet if they decide to ride a chocobo to their headquarters, Mognet Central.
While the Mognet doesn't make a true appearance, the Moogle Brothers will randomly mention they get their info from it should the player speak to them.
The player receives Mognet letters every day and can read them via the game's Calendar function. The letters often come with PP attached, and occasionally also give the player Friend Cards and special items, or even ask them questions. There are three main moogles: Linaly, named after the heroine of Final Fantasy: Legend of the Crystals, is new to Mognet and asks the player personal questions.
Benjamin, the protagonist of Final Fantasy Mystic Quest, travels to various Final Fantasy locations depending on the player's input. Mogstache, the original moogle, calls himself the Moogle Ragtime after the enemy in Final Fantasy IX and quizzes the player on previous Final Fantasy games.
Occasionally, the manager at the Mognet Head Office, a moogle drawn in the style of Kingdom Hearts moogles, will send a message to the player. The moogle added to Inward Chaos in the western release also resembles it.
Mognet appears again and is largely unchanged, apart from getting letters from different moogles.
