One more thing to add about the Liberalis Circulum. When the name is first mentioned in Issue 3, it's given an annotation that states this:

An old Latin word that the Assassins applied to those who were part of their Order. 'Ciculum' means circle. 'Liberalis' is a notion which pertains to free, honorable, and liberal men.

So it appears that we do, in fact, have explicit confirmation of Liberalis Circulum being the name that was applied to the Roman Brotherhood as a whole, rather than being an inner circle.
