Worldology is a pseudoscience that studies parallel worlds. Proponents of the idea of other universes often do their own research. The general public does not take them seriously, because usually 'researchers' rely only on their own visions and feelings.
The main character, Metr, sincerely believes in the existence of other worlds, despite the condemnation from those around him, but his interest in 'science' led him to other things. The player will be able to walk this path from the Metr's perspective... or maybe together with him.
