Skaven are found pretty much everywhere. The small rat-men don’t seem to form communities of their own kind very often. Instead living in the cities of other races, though they do tend to form groups together in those places. Their natural lifespan is around 20-30 years and they are very aware of the short time they are alive. Very ambitious and greedy because they know they don’t have the time to mess around. Many going to extreme ends to either prolong their life or build something to be remembered. It’s this general nature of greedy ambition that people remember and distrust.
They end up being pretty good magic-users when given a chance and it is fairly common for many to learn how to channel as a method of life extension. No particular style or source of magic seems to tempt them more then others. A very pragmatic race they seem to have a widespread ‘whatever works’ philosophy about everything and anything. Whichever magic a individual practices mostly due to either personal preference or simply whatever was offered when they were given a chance to learn.
