Magic is the lifeforce of all living creatures, and it is from it that all life is made - in areas with lots of undead, magic might actually be missing or weak, which puts a whole new spin on how dangerous the undead are. Even simple zombies can be troublesome if you're relying on mages and you hit a pocket of undead making a low-magic zone...
In the province of Behar in India, there is a bizarre custom that persists to the present day. Young men are kidnapped at knife (gun) point, and forced into marriage. If they refuse or cause trouble upon meeting their blushing bride-to-be, they are told that their family members will come to harm or even be killed if they resist. Some manage to fall in love or accept their fate. This scenario can be adapted to any rpg, ideally with a pc in the role of the abducted future husband!
