>>89709071so to avoid the void the flame needs to be lit up from time to time
and each lord of cinder is someone who managed to lit it up
and the ashen one's died trying to
so when you go through a "realm" it's basically you checking the place where a lord of cinder is chilling and the people that interacted with that lord
but like since you are going through the lords there are other people that also went through the lords so they show up multiple times
the idea is that you are advancing each lord's realm and after you the ones in firelink shrine you can go check the lord at the top and decide if you want to rekindle the flame or fuck shit up
