It's a bit outdated, but still a good starting point if you want to get into the lore of VALORANT. If any of the information in thet video doesn't line up with mine, don't worry. It gives you a basic idea of the world, and that's good enough to get into the characaters. Here is a good video by Necrit on the basic lore of the world. (Keep in mind that this is all a theory).
Enjoy, and tell me if I have missed anything out. Okay, so after listening to voice lines and analysing all of them, I've came up with this.
