All members of the Blood are separated into castes. It is part of who they are and often times rules their very nature. Their caste also determines their hierarchy amongst other Blood with Blood Male and Blood Female being the lowest, all the way through to Queen. Explanations for all of the castes, as well as where they rank in the hierarchy can be found on each caste page.
To view the pages, simply scroll through the sub-category gallery until you find the caste you would like to view.
