Within WA there a few ranks of Nobility, based upon ability, dedication and heritage. These ranks can simply be considered titles that members hold while they also hold an Legion Rank. Or these ranks can be their only rank when they exist outside of any Legion.
Lord (1 per House): The Lord is the leader of one of WA's great Houses. Generally either the founding member of a House, or an important and proven heir of that founding Lord. They have the ultimate say over how their House is ran and have an extremely high level of prestige in WA. Because of this the House Lord's rank is equivalent to that of a Captain.
Duke (1 per Minor House): The Duke is the Leader of a Minor House. A rare occurrence in WA, a Minor House is formed when a family/earldom become so well established that they begin to form branches of their own. Or if a clan outside of WA is merged into the Empire. In the latter case the Duke would be the leader of that absorbed Clan, in the former case the Duke would be the former Earl of the family. The Duke's rank is equivalent to a Commanders.
Earl (1 per Family): The Earl is the leader of a Family, or Earldom. Generally the oldest member of a specific branch of a House. They are the primary overseers of their family, and often times a families health can be directly related to the vigilance of it's Earl. The Earl has the equivalent rank of a Lieutenant.
Each of the Great Houses in WA have their own Order of Knights, that all go by different names. The Knights of House Dane are known as 'Rangers', the Knights of Dippity as 'White Knights, the Knights of Cammander "Alpha Pack" and the Knights of House Kilroy as "MechWarriors". Furthermore all Earls, Dukes and Lords also double as Knights. A Knight, alone, is equivalent to a Hersir.
Knight (Unlimited): A Knight is a proven and dedicated member of a House/Family. They have learned the history of their linage and have proven that it matters to them. They have been members of WA for at least 6 months and take WA more seriously than normal members. A Knight is a special sort of member in WA, supposed to be more chivalrous, more loyal and more focused on their House and WA than their non-knighted peers. A Knight also has the special and distinct ability to form a TRIBE. A tribe exists outside of WA's Legion system, and is primarily administered by the Knight and House. A tribe is sort of a micro-platoon. Made up a the Knight and two retainers(Thanes) and their Tribes recruits, known as Freedmen. It is hoped that eventually a Tribe become larger enough and stable enough to apply for Legion status.
Thane (Unlimited): A Thane is a non-Knighted member of a House, who consents to be a part of a Knights Tribe. They are full members, not freemand, and represent the logistic support for a Knight in his effort to create a Tribe. A Tribe is only allowed to have up to two non-knighted members in it, these being the Thanes. Any other non-knighted member who wishes to assist the Tribe must still be part of an Imperial Legion. The Rank is roughly equivalent to the rank Centurion.
Freeman (Unlimited): A Freeman is not an official member of the Empire, although they are an official member of the House. They are not fully civilized or accelerated members of the tiny micro-platoon entities known as Tribes. As they become more organized and 'WA-ized' their Tribe will either be officially made a 'rough platoon' in an Legion (Which makes them official members) or they can individually apply for full WA membership on the forums. The Freeman rank is the lowest rank in WA, lower than that of Conscript. A Freeman cannot be promoted until he is an official member.
