Draconic Magick Options

I've recently been involved with a gentleman who used to practice some form or another of Draconic magick in his past, which led him to forming a pact with some form of Draconic entity which co-habits his subconcious; it's quite an interesting arrangement, and he appears to be able to draw from this being's power at whim, or else simply let it control his body in order to perform rituals or spellworking.

In attempting to discern more information about this particular form of magick, I decided I'd ask here; does anyone have any experience with Draconic magick? If so, would you be able to recommend any literature or other sources that I'd be able to investigate? Any anecdotes or info you'd like to share?

I found a thread where 'Dancing with Dragons' was mentioned, which is one I'll add to the list. Is there anything else?

LOL great thoughts think alike! i've been wandering about possibility of a fungus deity for a long time,
A certainly i'm sure with the thousands of years of magic mushroom consumption among humans,
These topics have had me musing on the idea that maybe the distinctive souls of every living creature to have existed might be embodied in a kind of god-form.
I was thinking that a theoretical pantheon of identified prehistoric species could be a lot more powerful than the creatures of the pokimonicon..
Dose Deity get stronger with having had it's 'likeness' having actually happened in nature?

I can't say i'm in any great state of understanding when it comes to alternate dimensions, but serpose that all living creatures 'create' or become part of an after-life, or maybe just 'intelligent' life either way
their has been many great flushes of intelligent creatures existing on this planet, an often they die off on mass, but in a spiritual sense they would continue but would be unable to reincarnate.
The souls of the dead unable to participate in our universe anymore would stretch the fabric of our reality to form a new one, maybe not as powerful, maybe quite different, where the destruction did not take place.
I'm not sure believe that, but if i did i would see the 'fairy land' universe as being populated by the descendants of some of the many different species of humanoid that where wiped out by a big volcano.

Is their any real limit to the amount of reality's that could exist?
