Rift Beacons were objects that were used to alter Locations and bring back old and new locations. They were first introduced in Season X , when The Scientist used them to alter Neo Tilted into Tilted Town, a Wild West version of Tilted Towers. The energy used from the Rift Beacons came from the Zero Point.
Season X
Rift Beacons appeared in random locations every week, knowing that specific location will change. When new challenges came out, that specific location would have changed into a new location or an old location.
The purpose of the beacons was revealed in The End event. The rifts they formed were used by The Seven as a way to get onto the island and begin the event.
Chapter 2: Season 4
In Chapter 2: Season 4, they were repurposed by Tony Stark to spawn in new POIs and a ring of them were placed around Frenzy Farm and The Orchard. When Stark Industries was created as a result, they powered down.
