Still, given that the Overlords possess the Echo, which itself appears to hint at a soul that survived the whole dissolution process effected by the Lifestream, there may be some connection to this and tempering. Alternatively, the division may be along the lines LineageRazor mentioned, which also seems reasonable to me - or it may be a mixture of both.
