The Noble Expertise of Creating the Remaining Organism is a gentlemen's club. People who don't belong call it the Noble Expertise, or perhaps the Expertise, but the people in the club call themselves necromancers, and the club itself N.E.C.R.O.
Hi Ho, Hi Ho....not included
The Yugzhee, or "hedgehog-people", guard a great, secret treasure inside their giant burrowed lair. The mysterious Wall of Keys, a 12'x10', foot-thick, cold-iron, "wall", upon which, on iron hooks, hang 100 ornate iron keys of all shapes and sizes. Each key opens some heretofore un-openable barrier, door, or gate, in the particular game world of choice.
The PCs have come upon a great boon, except for the fact that the keys cease to function properly if separated from the iron wall for more than a few minutes. Higher level characters will be able to figure out how to take the wall "with them" via magic. Lower level characters will have to get creative.
