There is a pit in the brain series:
Suppose, in the Goblet of Fire plot, something went wrong when Voldemort was resurrected because Peter failed to pass the potion test.
After the thick fog dissipated, Voldemort found a familiar figure standing in front of him, with a face that was paler than his skull, big black-red eyes, a flat nose like a snake's nose, and many nostrils... The other person stared at him with a ghostly expression, and Wormtail had already fainted from the pain. He later realized that he was tied to the stone tablet and the wound on his hand was still bleeding. Haha, this was embarrassing.
