As with the magic, I voter standard power level.
I'll wait till Tuesday to do the final tally of the power and magic levels. It looks like we're going standard magic, but I'd like to wait for more people to have a chance to vote.
I do like the idea of the spellcasters looking down on the common folk as lessers.
Also, my idea of this is that since everyone is putting in there input, people can actually use this campaign setting. If you do, you can just modify it till if fits your style better.
For instance, if I were just going to use it, I could have wizards be incredibly rare, and incredibly powerful. Perhaps until a few hundred years before, the art of magic was lost to the people of this world, until ancient ruins were found containing tomes of spells of arcane might. Those few who were brave, or dumb, enough to read them gained incredible power, at the cost of there sanity. That would be a low magic campaign setting, because although there are very powerful wizard, common folk have little access to arcane magic. Perhaps the same goes for divine magic.
Standard magic: basically where everyone knows magic exists and most people accept it. There are court magicians, wandering mages, local witchs, etc. But the common folk might go generations with little or no exposure to magic of any kind. Magic is something that is pursued by only those who have access to it: you have mage colleges, and many wizards take on apprentices, but you must be very dedicated and fairly wealthy to pursue the art.
High magic is where almost everyone has been exposed to magic at some time or another. It is unexpected, but not uncommon, for more than one person in a small town to have knowledge of a few cantrips. There are vast schools dedicated to magic, and many towns have a small community of wizards, helping around with magic when needed. The most powerful of spellcasters are terrible to behold, with access to powers that others cannot dream of. Also, magocricies would be common. This is a government headed by powerful spellcasters: perhaps the king is an aged wizard or sorcerer, or members of his family or politicians are. In a high magic campaign setting, magic is common place, but not so much that commoners have any real access to it.
