A lot of RPGs use a specific term for their game to refer to the gamemaster of that game. D&D obviously has the Dungeon Master; the Storytelling system (used by Vampire: The Masquerade) has the Storyteller; Call of Cthulhu has the Keeper.
If Pathfinder was going to have its own unique term rather than using the generic Gamemaster, what should it be?
Pathmaker, and the players would be pathfinders
I was going to run a campaign in 5e during a primordial era, where the land is still shifting and moving. Since it takes place thousands of years before anything, I felt “adventurers” wouldn’t fit the characters, and decided “pathfinders” would fit in the setting, and was a funny little tongue in cheek reference.
Since that initial idea, I’ve moved on to playing pf2e, and if I ever run this campaign, am definitely going to keep that name going.
