im not very familiar with TES lore much and i want to start getting more into it, i want buy the books but with boarders closing thats kind of hard at the moment.

anyway back to the topic, my favorite race in TES are the Khajiits but ive heard a lot of things happening in the other provinces of tamriel and i havent heard or seen of anything happening in Elsweyr except for just seeing that it ceded from the empire after black marsh, so what has happened in Elsweyr?

You can start with the http://www.imperial-library.info/content/infernal-city-lore-notes on Elsweyr from The Infernal City, at The Imperial Library.

The Mane was assassinated, semi Anarchy occurred.
