@Stadenwick dude... if it's contributing to the worldbuilding then it's not a filler arc then
oh well, maybe we just have different definition of what a "filler" is
i stand by my point, this is not a filler arc because this is the result of Ainz's earlier doings and he's trying to fix it while also building a base of operation in the forest
skipping this thing is like killing one of the four heavenly kings and then nothing happened afterwards, not even any reaction from the other 3 left
i think people calling this filler arc are just here for a power fantasy manga, so they got bored because we get enri's pov most of the time
