Death by Dominion

[Jagdpanther]

I'm in the end-game phase of a SP game. I hold 2/3s of the territories. I have a temples in more than half of my territories and a half-dozen stone idols in enemy domains in land I hold. My total dominion keeps shrinking. Any ideas why?

Even my capitol, with a stone idol is slipping into enemy dominion.

(I am playing MA Ermor and the remaining opponent is Man.)
