Teleporters are objects seen in Phoenotopia. They are large chambers that are used to teleport people between two places. Gale is able to use them to access secret areas and skip over particularly long and grueling areas, although they only appear in a select few spots in the late stages of the game, granting her little opportunity to do so.
Two Teleporters are seen when the player first enters Ancient Crater. One is linked to the Phoenix Lab's entrance, and the other is linked to its core (the area just before the Computer Guardian). They become active once Gale reaches the lab's entrance and core, respectively; this was done because the Phoenix Lab is an especially long level, so the Teleporters were put in place to allow the player to come and go to and from the Phoenix Lab quickly and easily. This is especially useful for when the player reaches the Computer Guardian's room, allowing them to use the Teleporter just before its room to exit the Phoenix Lab, grab any items (e.g. consumable items with high healing or power-boosting properties) they need, and come right back to the room.
Another Teleporter is located in Fran's Lab. It only becomes active after Gale gives Fran 30 Moonstones, after which she will activate it and use it to bring herself and her colleagues to Hidden Village. When Gale uses it, though, she will be taken to Forgotten Forest instead, and must make her way through the forest first to reach Hidden Village.
A broken Teleporter can be found in the lower level of Ruth and Thomas' house in Panselo.
