So, are these the embodiments of Asha, or not?
Asha is the primordial dragon of Order and has three aspects.
Malassa is Asha's daughter, a dragon of Darkness.
Silanna is Asha's daughter, a dragon of Earth.
Elrath is Asha's son, a dragon of Light.
Shalassa is Asha's daughter, a dragon of Water.
Arkat is Asha's son, a dragon of Fire.
Sar-Elam was formerly a mage, then a dragon, now a skull, not a god but very powerful.
Urghash is Asha's brother, the primordial dragon of Chaos.
The Six Demon Lords are Urghash's sons, the antitheses of the elemental dragons; they have disappeared.
Kha-Beleth is the current ruler of Sheoh, possibly one of the Demon Lords, or their replacement created by Urghash.

I understand everything now; they really complicated the story, couldn't they have made it simpler? So, the glowing women are Elrath's daughters, for example; I can't imagine any other way to explain their appearance in Haven. Another thought just occurred to me: "elemental of light."
