The Astors
This secret order within House and Clan Tremere were supposedly set in motion by the Inner Council and is believed to be charged with the responsibility of ferreting out traitors and spies within the clan. Like an Inquisition or secret police, they operate free from the restrictions of tribunals and other legal apparatus and answer only to Tremere and the Inner Council.
The Astors have the right to convene secret "Astor Councils" where they exercise the right to summarily hold trials and execute offenders as they see fit. Those found guilty are sent back to Vienna to await appearance before the Inner Council.
They recruit its members from the Tremere ranks, choosing those that seem fit to shoulder this great responsibility. Absolute secrecy is required, and a member is expected to be able to answer summons to Aster Councils without revealing his activities to anyone.
