Whether it's related to this villain you and the others saw or not, nobody should be doing experiments in the sewers. Whatever is going on down there, you know it can't be good, so you head down to put an end to it. The smell in the sewer is awful, but you perservere. You look for hours, finding nothing down each maze-like tunnel, before you finally hear a sound which cannot be attributed to rodents or gentle dripping. It sounds like a growl at first, but it quickly grows to a roar. You brace yourself for battle, but when you see your foe, you know you can't win. Rushing towards you, leaving no room to escape, is a literal shit storm; a wave of feces and flushed matter fills the entire passage and is coming at you. You endure it, as vile as it is, even vomiting in your own mouth while fully submerged in the waste. When it's over, you don't even want to go on, not with your search, not with your dream, and not with sleep.
