Skaven have a strict hierarchy to their volatile lifestyle, and they will often use their position to exterminate any and all who oppose them. The only way to go up in their society is to murder your rival and to obtain his position in a sly or cunning way. They favor trickery or short-lived truces with enemies to which they will eventually backstab at a later date if they don't get backstabbed themselves. They always turn out chaotic evil.

It should be noted that due to these views and their tendency for back-stabbing, no one not even demons or devils, would ever want to count the Skaven among their allies. Everyone who knows about the Skaven knows that they are more likely to kick you in the shins and leave you for dead than even help a downed ally. Although a VERY rare occurrence of kindness can happen, given the right circumstance.
