They were explicitly given that name because they're not new characters.

The Beyonders exist beyond the universe. The Ivory Kings exist in the gap between universes (as do many of the factions in the Game of Worlds like the Mapmakers and Black Priests). The Ivory Kings are called the Beyonders.

Supposedly the Beyonder wasn't one of them even before the retcon that he was an Inhuman. The Beyonders are a concept that predates the Beyonder by a few years when they were mentioned in Marvel Two-In-One 63 as being behind Sphinxor moving Counter Earth.

The Beyonders were later revealed to be behind a lot of things in Englehart's Fantastic Four run. Commissioning the Nuwali to create the Savage Land, creating the Fortisquians (Comet Man's friend Max is one of that race), the power from their dimension was said to be the thing that powers Cosmic Cubes in Fantastic Four #319.

They sound obscure and they are but they are tapped into a variety of different story points according to Englehart's Fantastic Four run including the Savage Land, the cosmic cubes, the caretakers of Arcturus, the Fortisiquans, the sinking of the Deviant city Lemuria, the cat people, Master Pandemonium and Belasco. It was a horrible story but they have deeper roots in the marvel universe than is readily apparent.
