“ 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.”
“ By late afternoon, the sky starts to cloud over. The sun shines behind the fluffy clouds, gilding the edges and showing a Jacob's-ladder of rays streaming through the gaps...very pretty. Gradually the clouds shift into a new configuration: you realize with awe-struck, preternatural clarity that the clouds form a map of a coast-line that you know, against the blue sky as ocean: surely it's a Sign! Suddenly, the golden beams coalesce into one long ray that strikes across the blue. A star-like gleam flashes under the ray: perhaps it is an island? But the charts show no island there...who would want to hide an island? Who could do it?”
“ A race of beings actually IS invunerable while in adolecence. They age, but cannot be killed. A miniority of the race (1 in 20) does not become invunerable, but rather becomes immortal at some point in thier adolecence, and ceases aging while being vunerable to death in all the normal ways. Another minority (also 1 in 20) Permanatly becomes invunerable after adolecence, but ages twice as fast as the race normally does. There is no known way to test for which of the three traits an individual manifests and the three traits cannot mix, as they are tied to the same gene, as it were.”
