I didn't jump into posting the thread immediately elsewhere cause I wasn't sure if many people
would be interested in participating...
In the thread we would pick one spirit at a time, evoke it, and compare notes.
I recall there was an Armadel evocation thread based on similar idea on pre-hack OF, that was never reposted after getting deleted, IIRC.
Spirits could be any pre-existing grimoiric entities (at least I'd prefer them over artificial ones, personally) and evocation method would be up to practitioner to choose.
So, anyone interested?
