Well, I think you can already interpret a lot.
Elohim: an owl stands for the sagacity they gain by protecting the sacred places in the world and the white mybe their innocence, because they rarely start a war?
Kuriotates: The special bond between Cardith and the gold dragon Eurabatres is obvious
Bannor: umm.. a crown should underline the superiority of the people?
Malakim: ehh...
Luchuirp: The enigma seems to express their beautiful work, which they can create as craftsmen
Mercurians:
Ljosalfar: has the same source as the malakim... phew, no idea here
Khazad:
Lanun:
Grigori: they have the first hebrew letter of the alphabet: alef
Hippus: here, it is obvious again, a horse for the horselords
Sidar:
Amurites:
Balseraphs:
Doviello: it is a paw of a bear, which expresses the savageness of the people
Clan of Embers: a fire to honor their angel/god bhall
Calabim: a mouth with sharp teeth and blood around it
Svartalfar: a moon arising only at night supports the dark elves and their assassination activities
Illians: a snowflake for the newborn god of ice
Sheaim: theirenigma expresses chaos and honors their black dragon abashi
Infernals: a demon as a sign for a demonic people, very fitting
I hope you are able to relate my thoughts. For most neutrals I really had no idea what they could mean. They are just too abstract.
