I just had a random brain connection and thought of something kinda fucked up in a way that makes a lot of sense when you really think about it.
You know how mosb (the mountain of smiling bodies) was made from a pile of corpses that were left on the ground for a few days that became an abnormality eventually? Well the thought I just had was that during the culling of the lambs there dead bodies were all just left in a pile of corpses and that could become another mountain of smiling bodies.
Like it makes a scary amount of sense and if abnormalities existed in the cotl universe it would also be very possible for it to happen because their bodies were never really buried and considering how fucked up it is in the cotl universe this could happen (the bishops or their followers would do some fuck shit like that.)
If there is ever a l corp x cotl crossover (where abnos just start appearing not a complete merger where this is naturally occurring) this should be how mosb is created canonically in the au because it makes a terrifying amount of sense that this is how it would happen there.
