The appearance of the Omen Star in the first house of the sky bodes 'great things' for good or ill are about to happen. It is the rest of the stars that determine if it is for good and ill. Thus people are always looking for things to happen during the time of the Omen Star.”
“ 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 certain type of demon cannot not be hit by ranged weapons or attacks. Attacks have to be made up close and personal for the damage to mean something. Ranged attacks are to impersonal.

Spells: wizards might have half or no effect, preist might work due to divine intention.”
