I find that particularly fascinating (and yet another indicator of just how far you were willing to go to find source material). Although it also points out how far Mme. Blavatsky was willing to go for source material, inasmuch as the Deva is a Hindu figure.
I have been toying with the idea of putting together some sort of Angelic heirarchy to counter the Diabolic and Demonic heirarchies. Since we have arch-devils, why not arch-angels? Major Devils and Seraphim. Demon Princes and Saints... The details are unimportant, but you get the idea... And of course the "named" Infernal figures would have their own counterparts.
The only thing that has stumped me thusfar is in individualizing them sufficiently. Perhaps I am a creature of the mythologies to which I am accustomed, but the angelic hosts always seemed so... homogenous. Valkyries could work for one of the other alignments (NG, mayhap, although for those who know their true nature according to the Norse lore they are far from beneficient beings!), but I find myself at something of a stumbling block. And for the non-good/evil minions... I would ache for something more rooted in mythology than Modrons.
Any thoughts as to a possible expansion of the demon/devil/daemon idea into the realms of Good, beyond the (to my mind, rather limited) Deva/Plantar/Solar?
As always, my thanks in advance.
