I made a crest/badge for the RHC in my campaign. The wolf and raven reflect the colloquial name I've given the RHC: Wolfram Court. I wanted a somewhat more evocative name for the organization, so I have that they're commonly known by the name of their main headquarters in Slate, which is one of the seven old forts along the Delve river. It's the crest of the now defunct noble family, Wolfram, that used to maintain the fort back when it was still a defensive structure. The raven represents vigilance and wisdom while the wolf represents strength and diligence. I also have it that the RHC uses ravens as messengers and wolfhounds as K9 units. The city and number on the badge is specific to each Constable.
