“ A local sculptor of note has chosen to honor the adventurers by crafting lifelike statues of them. While he hopes to surprise them by setting the statues up in their home while they are off adventuring, he may have underestimated the paranoia of the typical adventurer.

“ 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.”
“ A Mimic in the rather unconventional form of a weapon, can be used as a weapon and grows more powerful over time. If introduced to the party early it could make an unexpected betrayal. Skittering around like a terrifying insect.”
