“ A secret MLM (pyramid) company that offers eternal life, but in fact it transfers the life forces of its members to those position 'above'. If you get high enough, (meaning you get enough new members) you start to enjoy the benefits. Maybe a willing sacrifice is much more effective for the transfer. But no one says, that a suddenly unwilling member, threatening to tell the authorities, may not loose it involuntarily... thus start people to vanish, and aged corpses are deposited somewhere safe.”
“ Mazetown stands right around the entrance to the Maze, and its whole economy depends on the people coming to visit the ever-changing and apparently sentient dungeon. They don't get all that many visitors, but the ones that do come tend to be rather generous in their spending; after all, if anything you take inside vanishes as soon as you go in, and everyone who manages to come out usually does so with fabulous treasures in tow, why not spend your coin on R&R before getting started?”
