what's the story about?

I'm not sure TbH HAHAH

I remember this is apocalyptic story and internal strife in their camp which doesn't even make sense. There's no clear end goal TBH And the apocalypse back story ain't even clear

Their plan is literally to kill off their protectors because they're too scared to leave and too hard headed to follow the rules. They're mostly doing this out of spite and revenge if anything
