Fine, I can do a proper breakdown. I was just gonna vibe on it, but... fine. So:
Ermor: Dom 4-7, Fire >= 4, Turmoil >= 1, Male
Mictlan: Dom >= 6, Astral >= 4, Death >= 4 , Fire >= 4, Blood >= 4, Magic >= 2
Pangea: Dom 4-7, Fire >= 4, Earth >= 4, Order >= 2, Male
Agartha: Dom 4-7, Earth >= 4, Death >= 4, Female
Fomoria: Dom 4-7, Earth >= 4, Blood >= 3, Production >= 2
Niefelheim: Dom >= 7, Water >= 4, Nature >= 3, Cold 3, Male
Rus: Dom 1-3, Death >= 4, Male
Kailasa: Dom 4-7, Water >= 4, Fire >= 4, Astral >= 4, Death >= 1, Nature >= 1, Blood >= 1, Sloth >= 1, Male, Maharishi
Yomi: Dom >= 8, Fire >= 4, Air >= 2, Astral >= 4, Nature >= 4, Sloth >= 2, Heat >= 1, Male
R'lyeh: Dom >= 6, Water >= 4, Astral >= 6; Magic >= 2, Female
I will add that there are a few titles among our pretenders that the linked list does not include, and there are also a few unknown requirements on some of the titles that were listed. [Edit: hmm, at least some of the missing ones ARE in the Epithet Explorer, though. I'll add the ones I just caught.]
[I feel reasonably comfortable with the accuracy my initial impressions of the list as far as paths and dominion went, but my uncertainty WRT the scale implications made me reluctant to actually try to spell out those impressions.]
