It is different, I'll grant that. Never been in a campaign where the chairman/princeps/disceptator rotated every quarter. I'd imagine it's probably pretty difficult for the mortals to wrap their minds around, too. But then, they'd probably go to the autocrat for anything, anyway – at least until they get used to the magi's Gifts.
Except for the bits about Apollodorus being Princeps Emeritus and his donations to the covenant, it's a pretty standard boilerplate charter straight from the book. If we have issues down the road, we can always amend it to fit our situation.
I remember throwing out a couple of ideas way back when, but there wasn't really any discussion, nor any other ideas brought out. If those are the only options on the table, I'm kind of leaning toward Mons Restituisse – mainly because of the play on words, with restituisse meaning both rebuilt and reformed. On the other hand, Mons Restaurata is easier for my English tongue to spit out.
