Considering that we are talking about rivalry between the Seven and Kas…
No, i could agree about CoC. Harsh conditions force you to develop yourself and develop technologies to a higher level, and according to Savin, Mareth was one big harsh condition on the verge of its death. Compared to Mareth, Savarra seems like a resort, no reasons to…evolve into something bigger than walking-talking dick/pussy life support system. Same for the other side: gods will take care of it, no reasons to do something. Oh, they choose a Champion? That's great, even fewer reasons to do something, Champ will carry us to the victory! Would the minos even scratch they butts if demons hadn't besieged Khor'minos? Would the boreal elves take their heads out of their asses if Kas hadn't come to their queen? Those who actually fight against the invasion from the start - loners who have suffered from it personally.
How does the Seven plan to win this? By betting on one person? And practically without protecting this bet? Well…gl.
Remember
that star wars reference of a quest. There 2 paladins coming afterwards. They knew that "there is a demonic invasion in Frost Marches" they come to check and more then a little shocked about scale of it. BUT forces from mainland will come in 2 mounts or something?
Seven already seems to have some consule about it and one of the points - or special soul. But as we see, Old Balhar need time to march, Lumina almost offed herself bc of her stupid decision with Godeater(who seem to be much more intelligent then one in Winter City).
They basicly repeat mistake of Mareth gods. They HIGHLY underestimated threat. We don't know how powerful real Gods are in CoC verse, but demon already won fight with them. Even direct confrontation.
Fact that Savarrah underdeveloped (thanks to a coincidence in the loss of MOST of tech that Belhar have and Nereva agency in preventing reserch in that matter) they gonna regret it. And in some bad end they are (like one there Kass ascend. But don't like it).
Incopetent gods, are so cliche that it almost hurt me.
"About gods take care" - they don't. Most talkative of them is Keros. Others don't interfere. Lumina saw some rando Wraith more important then lose of almost all of pale elf. Seems EXTREAMLY hypocritical, considering how she comment schism (also didn't give a shit about that they do to Glacial Rift). She care, she sorry, but didn't do dick for them.
P.S. if they so powerful as they try to look - why de fuk she didn't smite Kass in Winter City then she was given the chance. Drop stupid threat - and thats it.
