I just tried to nominate "Glorantha (Tabletop RPG)" as a fandom. Unfortunately, it seems to be synned to "King of Dragon Pass (Video Game)" which I also nominated and which is already approved. (The two fandoms are closely related but should not actually be synned; King of Dragon Pass is a spinoff of the tabletop RPG.)

Unfortunately, I can no longer edit my noms page because of this—it thinks I'm trying to nominate King of Dragon Pass twice and refuses to save. But that's why there are character and worldbuilding tags reading "(Glorantha Tabletop)" with no apparent associated fandom.
