The Mollys are not led by any one man, not since the demise of the beloved Republic.
The individual clans each hold their own, and work together in the Council to deal with issues pertaining to the entire Molly nation.
I am the Grandmaster of the Old Guard of the Republic, and a Councillor of the Molly nation.
That's as "boss" as it gets, unless of course you require the approval of the entire Council.
