For this to be official I'll have to post something properly in the GM looking for players section so that our campaign will have a proper spot on the board. But I'd like to have some guidelines first.
I'm not locked into Stonehenge or the Schism War. However, I do want to use printed materials from either 5th or 4th edition to save on some work. I have a pretty sizable collection of books, but only a few Tribunals. So here are some of the options for the setting:
If we want to keep it current, I'm fine with using the Rhine (Guardians of the Forest). It has rich possibilities for politics and conflict.
So the next question is the type of Covenant. Do we want to use some that are already in the Tribunal? Make our own? I favor making our own, as it will produce plenty of likely adventures. Then from there, what Season of the Covenant? I usually prefer Spring covenants, but the last time I ran one we started with an old Winter Covenant (the one I referenced in that link), and that was a lot of fun.
Then the magi. I think it's best if they start after apprenticeship. So that means a character that started apprenticehip at age 5-10.
Give me some input on these questions, then I can post something to get our own thread.
