Far to the north amidst the endless ice-flows it is rumored that a dwarven Walrus Totem clan exists. These rumors have been unsubstantiated to date, unless the dwarven sage Glurt Goblinguts is to be believed. He claims to once having encountered a troupe of huge dwarves, each standing a beard’s length higher than the tallest known dwarf. These dwarven “giants”, their hairy chins crusted with frozen shards of ice and dirt, hauled gargantuan yellowed horns or tusks upon their wide shoulders, and their helms, likewise, sported massive, down-ward pointing tusk-horns. Glurt Goblinguts later speculated that the impressive size of these dwarves was most likely due to their arctic diets, almost exclusively fat-based.
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!
Pirates' many bejeweled rings and piercings actually had a practical purpose - when the pirate or sailor died, the rings could be taken off as payment for a proper burial, saving him from a watery grave. This could be tied into regional culture, or made into a quest (The Pirate's Lost Rings, etc.). Also gives treasure-seeking divers another thing to look for besides crusty old chests.
