Sighting of a UFO was first mentioned in Occult Fan IV, a magazine that centers on bizarre and mysterious events happening around the world. The magazine hints on a special sidequest involving encounters of the third kind.
To encounter the UFO, the player must visit four different locations. A fixed battle will ensue (even with No Encounters equipped) and the UFO will appear. Once it has appeared, it will not show up a second time in the same location. The locations can be visited in any order.
The locations are as follows:
- Mandy Beach: The beach east of Timber. The UFO can be seen abducting a Moai statue.
- Winhill Bluffs: The UFO is sighted on Winhill Bluffs around Winhill. The UFO can be seen abducting a cow.
- Kashkabald Desert: Kashkabald Desert is in southern Esthar near Cactuar Island, and the UFO can be sighted on the western part of the desert, abducting a pyramid.
- Heath Peninsula: Heath Peninsula is in eastern Trabia and the UFO can be sighted on the small grey island east of the peninsula. The UFO can be seen abducting a crop circle.
After the fourth sighting, the player must fly the Ragnarok to Grandidi Forest in northern Esthar and land on the highlands above the Chocobo Sanctuary, and they will have a up-close encounter with the UFO. The party can choose to attack it - or Draw Demi. After it has been damaged enough the UFO will fly away. The party will get an Aegis Amulet for the battle.
