This article describes the symbols and colors of the more common organizations found within Bralspace. Any PC who takes Heraldry:Bralspace would know these without making a proficiency check, more obscure designs would require a check. Characters without heraldry should only learn these as they are encountered, or within the framework of the PC's background.
