My last PD campaign petered out due to two players leaving of 5, due to work, plus heavy coursework for me... too much work to pull together...
But I was going to work in "I, Mordred" elements in to it.
I was also thinking of never leaving phase 1 for tech purposes...
So, is Mongoose doing an Arthurian setting? If not, well, I might do some research!
Also important is handling the Catholic, Celtic, Pelagian and Gnostic churches right... and I dare say, RQ may be the best engine for that.
While waiting for my D&D game to go off (Cyclopedia Rules == B/X/C/M), one of my players decided to try CharGen... his commment as he was finishing up was "This is cool... why does it feel a lot like Pendragon?"
Tossing a few ideas about...
Initiate of Catholics would probably be subdeacons and deacons. In the 5th & 6th centuries, many were permanent, and many others went on to be priests; the celibacy rule was that once ordained, they could no longer marry; until the 1200's, most priests were married. Many monastics would also qualify...
The Acolyte level really compares best with Priests, Archdeacons, and Rectors, and somme friars ('tho friary was somewhat new).
The "Runepriest" would probably equate to major Abbots, most bishops and archbishops, and some archpriests.
Let's see, cult skills... Lore (Bible)*, Persistence, Influence, Language (Latin)*, Language (Greek)*, Sing, Healing*, and First Aid.
In case you are wondering "Why Greek?": Greek was the language in which many of the new testament books were written. Many of the Apologia (letters of explanation) were also in Greek. Much of scholarly writing was in Greek. Most lay members would not be taught greek, nor healing and first aid, but most of the clergy would. The term "acolyte" was in use, but I can't ascertain for certain if the lesser ordinations (Porter, Lector, Cantor, Acolyte) were actually ordinations yet... or just appointments.
