Orders within the Guild of Adventurers-Upon-Return (GoAuR)
Latin for literally 'A Pleasant Place'
Near the end of many a heroic venture or quest a brave band of adventurers upon return will find it necessary to seek out a sage, a wisened person, looking for the answer to a riddle, to decipher a map, or to unlock a geas or curse placed on one of their own. The strangest of quests, those touched by the madness of the fae, the eldritch influence of the outsiders and abominations, and those tainted by the hellish realms, are best met by the mysterious sage known only as Mugwort.
Chartered in Royal Year 618, the Guild of Adventurers Upon Return, was intended as a guideline to deal with and control the increasing number of men and women who were taking up arms and pursuing a career in heroism and adventurism. The guild would police it's own, and function as an odd jobs mercenary corporation, subservient to the crown, and supportive of the clerics.

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.
