I came across this website dragondreaming.wordpress.com and it has a lot of information for those interested in dragons and dragon magick.
Below is a list of dragon deities from that website. The dragons themselves are said to have revealed their names to practitioners of dragon magick. However, it is difficult to find the true origin of this list. Lady Thorn of the website Thorn’s Meadow credits Dragonfyre Weyr as her source. However, the information on that (outdated) site is now gone.
Anyway, I’m going to start working with some of these dragons. I already feel protected by my dragon guardian, so hopefully these dragon deities will bless me!
The following list comes from Dragonfyre Weyr via Thorn’s Meadow.
The Dragon names listed here were departed unto me by DragonKind, one of my dearest attendant dragons, my friend…my soul mate.
Dragon Deities
Gneicht …(nyte, long I) Dragon God of the Night, of doorways (both opening and closing them) and opportunities.
Veaug …(vog) Dragon god of obscurity and that which is hidden; does not like assisting in hiding actions or objects.
Morthan …(moor’-z’dan) Dragon Goddess of bountiful harvests of all kinds; mother aspect of Dragonkind.
Luqueas …(luk-wee-ass, long U, long E) Dragon trickster God; take great care when inviting His presence.
Tysteal …(tiss’-dell) Dragon shephard Goddess; guardian of the meek; a dragon person’s first line of defense.
Mordak …(moo-ór-dak) Dragon God of war, vengeance and retributions of all kinds; make dead certain that you are within your magickal rights before calling Him down, as he is not amused by a fallacious summons.
Davliteau …(dav-lí-too) Dragon God of conjured entities; very helpful in ridding one’s self of “sent” conjurations and the like; benevolent to the core; very helpful and willing attendant being, though He has little power in other areas.
Ryusan …(rí-u-san, long I, long U) Translates literally to “my dragon.” The sex of this Dragon deity is unknown to me; although I feel a definite feminine presence when it is near me, there are many male attributes present as well. Ryusan, of the three-headed Japanese variety, is best at consoling and nurturing a hurt spirit, whether it be in a host body or not. Ryusan has escorted several spirits on to their next journey for me. I am not sure what else this deity can/will do, but I do know that Ryusan can not contact those who have passed on, as I have attempted to acquire Ryusan’s assistance in that area to no avail, though I have received great comfort from Ryusan over the years.
Ouida …(o-weed’-a, long O, soft a) She often assists me when I am in need of direction. I do not know what She governs, or what aspects She controls, but She has proven Herself invaluable in the area of guidance.
Solange …(so-londg’) Dragon deity of healing. Though Dragons rarely become involved in human affairs, Solange cares about those who care for others. He will lend a healing touch to any beneficial healing spell, but there is a price for His assistance. He requires the planting of fruit trees (three at the least and 9 at the most) for his services. He will also attend to your herb garden and bless it with His dragon power.
I will likely not work with Mordak (and I don’t encourage anyone else to) since it sounds like you would only invoke him to aid in hexing and cursing.
As for Luqueas, I’m not sure what you would invoke a trickster dragon for.
Solange seems hard to work with considering his requirements.
This is a wonderful collection of dragon deities that I hadn’t seen before,
