Players seeking the hidden city of Mysidia in Square Enix's Final Fantasy Resonance must complete Chapter 5, titled "Scars of Time," to access the location. The narrative follows Rainn and his companions as they travel aboard a newly upgraded airship equipped with a radar system designed to detect magical concealment surrounding Mysidia. According to in-game dialogue, the radar functions as a treasure-hunt tool, requiring players to scan the world map for signal fluctuations that indicate proximity to the city. Lid, a party member, provides feedback on signal strength without specifying directional guidance until the player nears the destination. When the signal weakens, players are advised to alter their course; upon nearing Mysidia, Lid announces directional cues such as "Bingo! There's a hotspot to the north!" or "I can practically smell it! Just a liiitle to the south!" Upon reaching the precise coordinates, a cutscene depicts the city's magical camouflage dissolving. Geographic context places Mysidia south of the Kingdom of Pharm's western region, positioned between the southern tip of the main island and two adjacent smaller islands. The exact location is situated in the southern portion of the Kingdom of Pharm within the western map sector. This mechanic integrates technological elements with fantasy themes, reflecting the game's broader narrative contrast between science and magic.
