Welcome the curious....
What is the sacred order of the "Dark Raven?"
Well we have our own password, we have our own society, we are watching you. The Order of the Dark Raven was formed to watch guard the Guild members and to ensure they are following the Guild Laws.
The number of members involved with the Dark Raven are unknown and unpublished, as this would give away the secrecy of the Group itself.
SOME COMMON QUESTIONS:

HOW CAN I BECOME ONE? Well an intense interview by Master Nabolshia himself who is the mediator for the Dark Raven group, they key here is upmost secrecy and not mentioning that you are a member of the group to anyone except Nabolshia himself. HOW MANY ARE THERE? The number is unknown and always will be, assume all guild members you talk to could be a potential member of the Dark Raven.

DO THEY HAVE MEETINGS? They do not meet in a group..however a system is being devised do that they can and not reveal thier true identity The members of the group will be informed of any change in this...

WHAT IS THE BENEFIT OF BEING ONE? Well, you are basically like a modifier but for the Guild. You are rewarded with HONOR for reports of other members that becomes a fruitful one. Catching members breaking the rules or in the act of some other action not benefiting the guild. Thus you get rewards for catching others breaking the rules....

WHO KNOWS IM A MEMBER OF DARK RAVEN? Noone but Nabolshia, and once the mod for meeting others is in place, mention of your real name will get you removed from the guild for breaking your code of silence.
Nabolshia Master and Friend
