This is "is he gone" au, where black sapphire cookie dies. You are candy apple and You see Black sapphire slowly dying because pure vanilla when fighting shadow milk, accidentally hits black sapphire cookie and the other ancients are staring because They don't know what to do. Pure vanilla tries to revive him but it fails and he starts to cry. In this au, shadow milk doesn't know what he thinks of the other beasts and his servants/sidekicks, candy apple cookie and black sapphire. (if you like, you can add the beasts)
