“ 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.”
“ When a miracle is worked, when a God turns His attention to the mortal realm, the mortal realm is irrevocably changed by the Divine Presence. When this takes place through a living being, they become the Godmarked. Ever with one foot in life, and one foot in the realm beyond, they are emotionally and physically altered - always in a fashion that reflects the nature of the God that they have channeled - One who channels a God of the Winds may forever have a breeze lifting their hair, while a Goddess of Anger may blacken the skin and strengthen the body.”
