I guess I didn't ask my question clearly enough. Sorry about that. Let me try to clarify.
I understand that the PCs will become the Ring, as I do intend to run Company after Six Seasons. What I'm unclear on is the process of how they become initiated into the Company in the first place. The description of the Company's Initiation, as per page 85 of Company says "The Head and the Ring are present, as are all other Companions." Also, "The Head is given the responsibility of delivering the Charge" but when the PCs and the most important survivors of the attack on Black Stag Vale decide to form that Ring for the first time, there are no Ring or Head yet to perform the initiation, so how are they Initiated?
I assume that Shah’vashak will have to be more actively involved, but due to lack of experience with RQ and Glorantha, this will be my first RQ campaign, I'm unsure what form that would take. Does Shah'vashak manifest and act as Head for that first Initiation? Does he do so for the whole group, or just for his chosen priest, who then becomes the Head and initiates everyone else? Of course, my Glorantha will vary, but I'd still like some input from folks more familiar with the setting, especially those who've actually run that first initiation, as to how this should go.
