They are used to teleport characters to any other Teleporter in the dimension, but only once the recipient Teleporter has been tracked down and activated.
They also function as auto-saves and checkpoints for the game.
Use in the story Edit
At the beginning of the adventure, the crew attempt to escape an SS Souleye that is currently in some sort of danger. They all escape through the Teleporter on-board, but it malfunctions and sends them all to random locations around the dimension, with some ending up luckier than others.
After rescuing the second, third, and fourth crew members, the end-of-level teleporters will malfunction and send both Viridian and the rescued crew member to the Polar Dimension (with the exception of the fourth rescued, where only Viridian gets diverted.)
