Pythium speculation

[WraithLord]

Since Pythium is my favorite nation I wonder how does it make the transition to dom-III.

In dominions II pythium is described as a splinter nation of Ermor, and that the split happened before the catastrophe that had hit Ermor. Also in dominions II there is an additional pythium theme - "serpent cult", supposedly created after the fall of Ermor.

It would seem likely that, if the two current themes are relatively unchanged, either pythium will not exist in the first era or that there will be a new "theme" for it. In addition it seems likely that base pythium will be available at the mid era and serpent cult at the late era.

So...
Will pythium exist in the first era?
Will the current "themes" be changed?
How would they map wrt to the eras?
Will the backgrouns story regarding Ermor and Pythium be expanded/adapted for Dom-III?
