Yetensla is a system of mountains whose geographies slowly shift. Nomadic tribes familiar with Yetensla say the mountains speak to each other through moans and creaks. They clash, drift apart, and embrace at a time scale invisible to the human observer. And we are invisible to them as we live entire lifetimes in what seems like a few seconds. The only near interaction is the occasional appearance of a city that quickly crumbles the moment before a Yetensla mountain tries to touch it.
