The Unlimited Bladeworks is the secondary branch of the Blood Guard and has not yet been fully defined. There are several groups within this division that have been relatively flushed out.
The overarching name is The Bladeworks, mainly dealing with combat. Within this division, smaller groups exist such as The Knights and The Blades.
The Knights consist of certain individuals from the TV series, Merlin, but have been repurposed and much of their history has been altered.
The Knight of Courage
The Knight of Valor
The Knight of Strength
The Knight of Wisdom
The Knight of Will
The Knight of Honor
The Knight of Loyalty
Of these Knights, the first three are often found on Sol side and the last three are usually within The Realm. The Knight of Wisdom mainly stays transitory, going to whichever side where he is needed.
The second group are The Legendary Blades, most commonly referred to as The Blades. The Leader of the Blood Guard is also a member of this group, but usually remains with his fellow Hollows. This elite group is loosely defined but does have several members already in place.
I'm trying to keep the Guard from becoming too defined as to allow as much wiggle room as possible. It is quite the hassle to rewrite an entire universe just to insert a single character which is why having less definable borders is a great writing technique.
As more characters, information, and histories are added, so too will there be updates in regards to everything within The Unlimited Bladeworks.
