“ An African tribe called the Ik throws their children out of their homes once they turn 3. They are left to fend for themselves with no help from their parents at all, and to survive, form groups with others their age. These groups only last a few years, and every so often the individual will join a completely different group.”
“ The secret for immortality has been discovered by an eccentric wizard/mad scientist. Its found you need to reapply once a month. As people stop dying, and the birth rate increases exponentially, people are forced into homelessness, because of the need for food reamins the same, and food is not being produced fast enough to feed the undying population. The PCs have to find the creator and kill him, and destroy production, to save the world from undying, unending torture from hungryness.”
“ The seafaring people of the Southern Islands value their ships greatly, as do other maritime nations. However, they take the beliefs about ships a bit further. A ship's name is very important, once it is named it shouldn't be renamed anymore, ever; most renamed ships seem to fail sooner or later. Ships do not tolerate parts from other ships, a single board from a wrong source can cost sailors their lives, so it is said.
Most ships are identified as female, very few as male, though there is no tale of how their personality is identified; it has nothing to do with the name, for example. The Clarissa (a well-known male ship) is said to like good wine. So whenever sailors or passangers drink, they have to spill a glass for the ship, too. But that is only the most known example.”
