“ Mining in a certain area turns all exposed skin (maybe just parts that are actively disturbing the chemicals that cause the reaction) of the those doing the mining to a dark blue color. Will wear off taking as many years/days spent in the mine. ... meeting a party of blue-skinned humans armed with pick-axes etc. Strange disease? Demon offspring? Curse? If they meet only one ex-worker, they will very carefully listen to any stories he says, no matter if drunken or insane, or just makes up to get a beer.”
“ Swords form a bond to their wielder. A symbol on the grip that is absorbed through the user's hand and appears on the back of the hand. Maybe only visible to them or others that have the abilities. Could give unique powers depending on when it happened and what they did to get it. It takes a specially made sword that only few can receive and made by a certain race. Then they must do something really heroic to unleash the swords power. Once unleashed it is theirs till they die then the sword goes dormant again till another accomplishes another feat.”
“ The local temple is known for putting words of wisdom of stele, in and anround the temple. These words of wisdom are normally temple proverbs or wise words, but sometimes they are 'singing the praises' of any large contributor or a noble who grants them a special law. If you need proverbs and quotes for them, search a few quote and proverb sites, concentrating on religions like the temples. Put these quotes in a word doc or list, that way you can always 'whip out' a bit of wisdom.”
