Urbants-Creatures that move quickly around on their massive arms, and their "legs" dangle about from their torso, at about elbow length. They can move fairly quickly, but not as fast as an obese human, and can "jump" fairly high. Their "legs" are very powerful, and can kill with one blow. The bad thing is, Urbants cannot block attacks at their heads, which have relatively no neck, from the length of their legs being so short.
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.
