Commoners have lived on Earth since the beginnings of the fae. Trapped here after the Shattering, they survived by placing themselves in mortal forms, undergoing continual reincarnation. By being born and reborn into human families, they have both protected themselves from the worst effects of Banality and have developed close ties with humankind.
Nobles consider commoners to be lowly and tainted with the trappings of mortality. Commoners see nobles as arrogant and unfeeling, concerned only with power and status. Although some commoners and nobles may like and respect one another as individuals, in general, the two classes of Kithain share a mutual distrust and dislike. The Treaty of Concord enforced the feudal system on commoners, but most of them still do not fully adhere to all of its strictures, privately rebelling against the more onerous duties relegated to them as "lower" Kithain. Most commoners pay lip service to the local lord while reserving their own private opinions, considering themselves fully the equal of any noble.
