The Abyss Watchers

You're an ashen one (Dark souls III) making their way through the kingdom of Lothric. You've already fought the old champion, Iudex Gundyr, Vordt of Boreal Valley, and the curse-rotted greatwoos. You've trudged through the dangerous poison swamp of Farron Keep, and you're on the path to linking the fire to hopefully restore the fading fire in the broken, apocalyptic world of Dark Souls. However, you have now encountered a group known as the abyss watchers. You aren't exactly sure who they are but they're lords of cinder, meaning that you have to take them on. They're all dressed in the same armor and colors, and they're dual wielding daggers and swords with amazing martial prowess like it's no one's business, but they're outright slaughtering eachother. Suddenly, they notice you, and the boss battle begins.
