I just got a boastful message in my current game from Altar's leader, that he's begun the Spell of Morion, and is about to take over the land. Now, if I recall correctly, Morion is the swamp god whom I defeated two games' back, and there was no spell attached to it. The thing was defeated, and there was a benefit that could be placed on a specific city. The swamplands opened up to access. That was it.
Anyone else heard of a Spell of Morion?
