Dolmen happens inside a sci-fi world where humanity has colonized several star systems using space travel technology and genetic manipulation to adjust to the circumstances. The Revion product is distant in the primary lived on part of the universe, but came the interest of Zoan Corp. for emitting radiation not the same as others, suggesting the presence of other universes. Mysteriously, there’s just one planet within this system, that was named Revion Prime.
Prior to the discovery from the Revion system there wasn’t any evidence for the presence of other dimensions. The scientific and military interest behind this discovery could destabilize the present political balance but, in addition to that, research on Revion Prime also revealed the presence of an alien species known as Vahani – whose role seems is be to roam the universes helping other species to evolve. Their interests are obscure, also it remains seen if the development of xeno-species might have had any influence from their store.
