Very interesting. I love that nuance on the spell where you can trap people in a cell as they pass through a door, that’s quite chilling! Very evocative. The summoning of demons to do various specific tasks is very characteristic of 17th Century magic ala Lemegeton etc. as I’m sure you know.
The spells in Superno are more based on certain of the 15th Century and earlier grimoires, in fact some of them are actually direct (though modified) copies of a few such spells, which typically involve complex rituals the first time but can be used with less elaborate setup subsequently (though not necessarily at will). There is of course a heavy emphasis on talismans and charms, which probably peaked in the 16th Century I guess but certainly goes back to antiquity.
I wanted to use the (to me) rather engaging elements of the earlier anonymous / clandestine type grimoires, some of which are just now being translated and published for the first time, rather than the better known to the esoteric tradition in the 17th-19th Centuries. I didn’t focus too much on the Goetic demon summoning partly because the earlier manuals focused a bit less on it, and partly because I don’t want to encourage or contribute to young people plunging into that kind of thing.
Not against studying it but as you know there is a long tradition of the abuse and misuse of these traditions, frauds and charlatans and scam artists, and overall a fairly dark ethical atmosphere to it all. It can be approached in a much more nuanced way but I feel that ‘path’ has a lot of pitfalls, so to speak.
There is also something almost Vancian in the mnemonic traditions of Lull, Bruno etc. which is close enough for comfort, so I felt I could rationalize not departing too far. I like to let the people who buy my books keep a lot of different options so they can use them in different ways. If you want to stick to something more like traditional DnD, you can, if you prefer to go more realistic or go off in one of the many directions available in traditional mythology you can do that too.
I’d like to do a series of these books focusing on traditions from specific regions. Are you from Spain? I ran into a lot of fascinating esoteric material and mythology from Cantabria in particular, but the Iberian peninsula is very rich in such traditions all over.
