Aetheryte
“These massive crystals can be found throughout Eorzea, allowing adventurers to travel great distances in an instant. When first attuning to an aetheryte, adventurers will learn the spells Return and Teleport, which are necessary to use these aetherial constructs. For the ever-wandering adventurer, attuning to as many aetherytes as possible will ensure swift transport to nearly any location.
The Aetheryte system within a city is called Aethernet. Return and Teleport are actually learned when attuning to a player's second major Aetheryte.
As of Patch 4.57, the main Aetherytes in the starting city-states (Limsa Lominsa, Gridania, and Ul'dah) can be used to visit other World Servers.
A Residential District Aethernet is available in each city-state that contains a player housing area, allowing players to teleport to specified wards in the residential area.
Teleport destinations
Free Companies with housing can place an Miniature Aetheryte housing item on the outside garden: when the item is placed, its destination is automatically added to the Teleport list.
Attuning
When you attune to a main Aetheryte, its location will be added to your Teleport destination list. Attuning to the Aethernet Shard will add its location to the Aethernet destination list. When you attune to all existing Aethernet Shards of a city, your Aethernet list will get the city exit gates as new teleport destinations. Some aetherytes be visited but not attuned to unless the player has sufficiently progressed in the Main Scenario Quests.
