The Riftbeast

The Riftbeast was once a sentient portal with many facets, scattered all over all worlds. It was created by Aeiea herself with one purpose in mind: put people into the worlds that they belong in, into the world their destiny requires them to be in. However, due to how it operated, people took advantage of its portal-like abilities to send people into alternate worlds whether they belonged there or not.

The Riftbeast was mercy killed by its own Heroes in October, 2017 on the Day of Heroes. It now exists in Listr's realm with its love, former Hero of the Rift Olivia.

Methodology
The Rift's "victims" were always chosen for one of the following reasons:
 * They were hunted by the Rift itself due to not belonging in the world they existed in (by some divine mistake of birth, a complex destiny, or something similar)
