Nice work !!!

It may seem like nitpicking but I believe it would be appropriate to add comments like this :

For Ulm/BF and Ulm/Iron Faith : "Lose drain immunity"

For Pangea New Era (the list don't do this theme justice, imho, it's pretty much what the special dominion is about) : "New era basic troops have better and cheaper equipment than their base Pangaea counterparts but their mage and priestly troops are weaker" (not sure if you want to elaborate : the dryad lose 1 holy level, the pan lose on earth level)

Also I don't think it is worth mentioning in the document, but iirc Spring and Autumn Celestial masters gain the flying ability.
