I want to make a campaign based around the AD&D action figure line manufactured by LJN in the 80s. (You know, the one with Strongheart, Warduke, Zarak and the rest - you can read up on it here.)
In the setting, those action figure characters (hereafter abbreviated AFCs) would have turned against each other long ago. The power players of the world would be the relatives and descendants of the AFCs, split into squabbling factions - let's call them Houses - each of them jealously guarding the relics (remains, weapons, armor, etc.) of the old heroes and villains. None of the Houses would have complete sets of any one AFC's relics - centuries of squabbling, betrayal, and theft would have scattered them across the factions. In fact, the years have led to much confusion as to which AFC used which relic. (There could be bizarre religious schisms over whether a particular relic-shield was carried by Drex or Deeth in the olden days.) Furthermore, each House would maintain massive dungeons where the relics were housed and guarded.
If I wanted to get really weird, I could say that dungeons (and maybe even the monsters guarding them) are actually spontaneously generated by the AFC's relics. I like the idea of a dead adventurer's tomb slowly burrowing tunnels into the earth, sprouting monsters and traps like a seed sprouting roots...
Anyway, the player characters could be the official dungeon-delvers of a particular House, or be free agents hired by the different Houses to raid other Houses' AFC reliquaries. There could even be a secret "House" comprised of the descendants of the AFC's disgruntled followers and henchmen, seeking to claim the relics for themselves, or destroy them to spite the Houses. There would be many other "official" delving companies as well as free agents, and these could comprise the primary antagonists of the setting.
So, there you have it. It's sort of metagamey, I guess, but the idea has a certain wacky appeal to me. Any thoughts?
