I agree with the points above that if Letum Frigus spawns far away from the Illians, it usually means they become devastated when The White Hand completes.
I'd also like to mention the Throne of Hell and Temple of the Hand still gives bonus specialists if Letum Frigus is near, which is impossible now as it transforms into New Mulyr, and even if you raze it (to transform it back into Letum Frigus) the city-prohibition near it prevents you from gaining those specialists anyway.
I still believe locking Auric in a city is the best way to handle his suicidal tendencies, and either slap Cloistered on him if he's an AI or give him a smaller flat penalty to city defense to make it more likely other units defend first (after all, they should die for their god-king). The Channeling promotion(s) alone aren't enough to discourage him defending due to his high strength when he gets going with Combat promotions.
I think his huge withdrawal chance isn't enough for the AI to keep him alive; if he's to be allowed free roam out of his cage i think he should be given withdrawal promotions typically unavailable to his unit class to boost it to 100% if that's possible, so he
must be cornered to be killed.
Okay, I admit that I didn't play attention to which fire nodes were built by the Illians, but I thought maybe 1 was originally fire, but I think all 3 may have been from Clan lands. Eternal fire was definitely Auric, and somehow the Clan didn't build it. It was a very implausible game so that may have happened. I think the Amurites may have built them. I might be entirely wrong about those nodes due to unlikely historical circumstances, so my bad if it's not the game engine's fault. I wasn't playing an Erubus map because tundras and ice are much worse starts there.
I can't recall an instance of having seen Auric build a fire node from raw mana, but i do know he will build nodes on existing sources.
The lack of Dragon Cult by Divine Essense in that game was disappointing, but I hardly needed a buff. In a previous Calabim game, Wyrmholds were much more accessible early on. I thought someone more advanced did Stur from Slumber, but when I went on global conquest, no one was nearly as advanced as that. I still don't know how everything works with dragons, and I don't know what happened in the game. Did the barbarians do it?
The barbarians nearly always get the Wyrmhold via Acheron's spawning, but now that you mention it i don't know how if it's possible to found the religion if you don't have the cult pre-established (or happen to play as Tebyrn, Cardith Lorda and/or Kuriotates). I am unsure if you can get Dragon Fanatics via lair exploration, as i've personally always just conquered Acheron's city or waited for the Cult to spread to one of my cities (to then build my own Fanatics).
Also, would Dragon Cult be a canonical Plan B for the Illains?
Well, mechanically Winter Dragons still require White Hand state religion (although Drifa actually doesn't), but if you mean from a lore perspective i can't help but think they would still continue to worship Mulcarn / Auric after his death. An Illian society without winter worship wouldn't really be Illian, i feel like. After all, Mulcarn died and Winter found a new host in Auric; what's to say a new inheritor won't arise again?
Still, if you mean other religions to adopt in-game, only the original 7 have blocked features. They can even adopt Ember Legion without issue, hilariously enough.[/QUOTE]
