Hey all,
So one of the ideas that I have always had a love for was the concept of placing a Genii Loci of a place. I remember getting the Mystery Cult book and reading the Guardian of Nature (pg. 105) major virtue and falling in love with the idea of a magus who was transformed to be the spirit of a place. I then remember getting the Magic book and reading the section on Genii Loci and falling in love with the concept all over again. Even the movie Stardust gave me ideas, the idea of the wall leading to a vast world is similar to a portal to a regio, and the fact that the rulers of the nation are linked to their kindgom is also kind of like a spirit of a place.
Ars Magica is uniquely situated compared to most games in that its magic system is designed pretty open ended, that almost anything is possible with but a moment of thought and figuring out and tinkering with what was written. For some ideas it would take a long time to develop, for others (like this one) all the tools are already described and it just is a matter of putting things together. The idea for a campaign is not one actually set in the Ars Magica universe, though it uses its rules.
The idea is that once long ago the World was a single vast majestic magical garden, but either due to war or deprivation or the horrors of mankind the single greater garden was split into a thousand thousand pieces. These innumerable shards of the once all-encompassing Garden were surrounded by the dregs of mundanity, the places of the mundane mortal world. For these garden shards to truly survive they need a guardian spirit, a watcher and tender who will work tirelessly to enable the garden to survive, to prosper, to grow larger than what its original fragmented piece. Some of these guardians are sites given power - the most basic of spiritual forces - while the greatest have humans transformed through a mystical process into a genii loci, one known as a Gaian. These figures of power can be backed by four sources of power (the realms of Magic, Faerie, Divine and Infernal), though all four are part of the once greater united whole that existed in the primordial times of the Earth Garden. Though one of the Gaians cannot truly leave their place of power, their home, their sanctuary, their Garden, they can imbue small pieces of themselves into objects and creatures and then travel around the mundane world with said focus.
Story arcs might include working with the Gaians of other Gardens to try and create a peaceful relationship or to further the goals of the group. Covenants can still exist, being an alliance of Gaians who share a common goal and a common meeting place where they all may gather and created using fragments of their greater power. The alignments of Magic, Faerie, Divine, and Infernal quite clearly provide story lines and both positive and negative relationships between the various groups (though I would remove the utter potency of the Divine, the idea that the primordial Earth Garden was all in one, not four aspects working together and apart).
The magi-level character each player would have would be a Gaian, while the Companion level character might be an human agent or supporter who knows about the Gaians and wishes to support their continued existence and the majesty that they bring to the world. Grog-level characters could be the animals that live in the Garden as well as the human inhabitants to might conceivably live in the villages that could theoretically exist in and around a particular Garden. I could even see allowing a Gaian to have the Gifted Quality and know 'Hermetic' Magic, representing that they are able to utilize the natural magics of existence to effect the world - strongly in their own Garden, at normalized levels outside of it, and pretty weakly in the Garden of another Gaian.
Those who read this, if this concept strikes your interest I would love to have a discussion in terms of campaign organization, magical rules, and story lines. I think theoretically it could be pretty fun, and like I said it has been one of those (of many) ideas that have been peculating in the back of my mind for years now. hehe So yeah, I would love to hear what you all have to say on this.
