I really want to know what the Potterverse is. Is it just another synonym for the Harry Potter fandom?
The Potterverse is:
The fictional universe which is the setting of the Harry Potter series.
It's a fandom slang word for the world of Harry Potter.
Generally speaking, [person]-verse is often used as a fandom slang word for the fictional world or universe associated with the person. For example:
- the Whoniverse is the universe of Doctor Who
- the Buffyverse is the world of Buffy the Vampire Slayer and Angel
- the Whedonverse covers the world(s) of Joss Whedon shows and movies, including the Buffyverse, Firefly/Serenity, and Dollhouse.
