Deep Highstorms

[Aeshdan he/him]

Alright, my theory is this. In the beginning, Roshar was a perfectly ordinary grass-and-earth world. The Highstorms still carried the Light, but were no more powerful than Earth thunderstorms. So then Odium comes along, thinks "Cool! Thunderstorms" and puts a bunch of his power into the storms, turning them into the monstrosities we see today. Cultivation reacts by raising the Mountains of Mist to protect Shinovar and changing the biology of the rest of Roshar. Honor can't cut stop feeding the storms because that would mean no Light.

[Ari he/him]

Interesting, for sure.

I've wondered if the intensity of the highstorms might also have had something to do with Honour's death.

[fiveAM he/him]

Hmm, that seems entirely possible. I like it. Also, whenever i read the description of the Voidbringers attacking makes me think about how storms start, swiftly and devastatingly.

[Commander Spoonface he/him]

I've given some thought to this, as we see a similar thing happening in Mistborn. Scadrial was an earthlike planet until TLR made the Ashmounts, etc.

I like to think that this is just the way Roshar is, because that opens up an avenue for other Shardplanets to have all sorts of funky stuff going down.
