On a related note, are there similar internal groups among some supernatural creatures' communities, [@StormWolf]? Typically this is associated with say, mages and vampires, so to use them as an example, might they send their own forces to support the Sentinels because of their mutual interests and the extreme stakes presented? A sort of dubious alliance bred out of necessity and only deferring to the Sentinels because of their obviously much smaller scope and capacity?
