10/10 would not want to go to war against the pre-telchines
The Proto-Telchine resource war came about after many years of a cold war (the politics of it long lost to time). All sides of it were prepared to make sure the other never returned.
Modern Telchine estimates state that about 90-95% of their global population was dead within 12 hours of the first nuke launching. Those that fled to fallout shelters ended up staying for years on end as the global climate became unstable & made it impossible for Proto-Telchines to survive on land. Farming? Forget about it. Dust storms would dig up a solid meter of soil every time they blew by.
Many of those that fled to the oceans died of starvation, as the over-fished ocean life had long become weary to them. Still, some survived and slowly warped into the Telchines we know today!
