Rift-Stars are a type of luminous body in the Crossverse.
Unlike normal stars, these are formed from a hydrogen cloud around a Dimensional Rift to a birthing universe.
The gravity of the new universe attracts the hydrogen and heats it up. Any helium sinks within and is pulled through.
Julth feed off these stars, though these are less hot and magnetic than the Julth would like so less palatable.
