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?

It is hard to say for sure from your description of the gentleman in question, but having a dragon as his totem or power animal might be what you are describing. That isn't uncommon. Other than that I don't know much about draconic magic as you call it.
