Aleph-1 is responsible for the Waveworn Phenomena known as Void Storms and by extension the Voidworms. As of now, there’s no known way to directly counter the entity other than the Exostrider. However, there are technological advances that allow people to resist Void Storms to a degree.
Currently, as of version 3.0, it is the main entity responsible for Rover’s frequency loss.
According to the Royan Trine Myth, it is said that the Exostrider will reawaken and, alongside humanity, strike at Aleph-1 in an attempt to define a new Epoch.
