Repeat with me: "Thou shall not read all the hedge wizards of Ars Magica if you want to remain sane and not think too much about cool and alternative character options". repeat it a hundred times. There you go, an Ascetic Ritual prayer. :mrgreen:
While I await responses for the Heron of Alexandria Mechanica thread (if any), I was looking at the other characters that I have always found ultra-cool (besides those in HMRE): Spirit Masters. The Witches of Thessaly are one of the paradigmatic summoner traditions out there.... and here is where I found something weird.
In their description it says that their dwellings are protected by powerful spirits. I thought "cool!!"... and then felt quite helpless when it came to see how they would bind them to their dewellings to have them protect them
There are several options here:
They are not bound. The witches just bargained with them (summoning skill + normal bargain) and they agreed to protect the place
There is a use for Commanding that I am not seeing.... Commanding is limited to protect a particular witch, not a place, and only for Sun duration AFAIK
Some of them have Binding. That would be quite normal IMO*. But then I am not sure that Binding can achieve that either AFAIK the spirits are bound to persons or items, but you need to carry the item with you to use it: the spirit cannot act on his own initiative when bound. (as a side note, I guess that some of them might have Ceremony as well, to achieve a high casting total to summon and bind powerful spirits)
3.1) Could it be possible to bind a spirit to a location? And have them act on his own desires even if you do not control the item explicitly?
3.2) Could it be possible for that spirit to act as a Guardian Spirit for the place?
I have not checked it, but IIRC Fudarus has the same kind of powerful guardian spirits linked to the place, and so I am curious on how they achieved this.
