Hehe, I love the idea of naming the hero Morpheus. To be honest, I'm actually not quite sure whether it's possible to make settled great people in worldbuilder... That might be a problem with my quest reward for the AI civs, come to think of it.
By the way, I've been thinking on how Ceridwen's schemes to destroy the world might intersect with your mega plot later on... One idea that comes to mind is Ceridwen trying to convince people that since they're (allegedly) in the vault of the god of lies, any way out is really only going to be a way back in; and that therefore the only real way out of the vault is to destroy it. Maybe we could flavour the Prophecy of Ragnarok like this, for example: it's not a prophecy of the end of times, but a pact to cause it. And every unit that follows this pact therefore commits random evil acts in life (hence the increase of the AC) in the hopes of them all adding up to destroy Esus' vault.
