The VDVM relies on secrecy as its primary weapon. As a result, it is organized into a heirarchal scheme of semi-autonomous cells:
Ul'Veldriss - arch shadow mistress - leader of the VDVM
Drada Ssivah - adjutant to the Ul'veldriss -
The Drada Ssivah is the mouthpiece of the Ul'Veldriss. Her role is to relay the orders of
the Ul'Veldriss to the Valsharen Vel'xunyr and, in turn, relay their reports to the Ul'Veldriss
This is usually done through magical means, or internal memos of the VDVM - offcially -
the Drada Ssivah s nothing more than a paper pushing bureaucrat.
Valsharen Vel'xunyr - Royal Spy - these agents are the inner circle of the VDVM.
The Valsharen Vel'xunyr are from the Noble Houses - one from each house (as a general
rule); however, betrayal and skill can alter this. They each have a certain number of
deputies that act as their inner circle in performing assigned missions and their own
Vel'xunyr - spy - this is the beginning of the outer circles of the VDVM and report to the VV
Trisil - agent - these are the foot soldiers of the VDVM and report to either the Vel'xunyr,
or higher ranking agent.
Trisil recruited by a Vel'xunyr are "Ust Trisil", then successively(if the Ust Trsisil is
authorized to recruit more agents by their commander) drada, ilarnbus, quenar, etc.
ooc - I recognize that this may not be how the VDVM has officially been conceived, but it seems an effective way to include all the players who would be interested in participating, assure maximum secrecy, and infiltrate every aspect of Drow life. Also, membership will not be posted publicly except for the Drada Ssivah since that position holds no authority and is the public face of the VDVM.
