I lowkey kinda made a peak story for an elder scrolls set in black marsh

as we all know black marsh is toxic with millions of disease to everyone whos not argonian but we also know Bethesda doensg like limiting race options so i have an idea

What if memphala(her because shes basically backround daedra so she needs a mainline game) somehow is corrupting the hist and draining the trees of life and the trees cant use argonians that are already in blackmarsh because theyre a part of the hist so they can't even hit memphala while shes corrupting it so the hist needs to summon a hero from whatever outside province you choose and whatever race you choose and you need to defeat memphala and youre immune to the diseases because of the hist power's which would be this games version of shouts
