“ 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.”

“ In a small farming community, the only way to cross a river is to basically pole vault across. A small section of river has a small raft on a string to pull items across but for a person to cross they must use one of the many provided poles. Might be interesting seeing what the players do when they come across it. Villagers do it all the time so are skilled and can do it with ease.”
