“I am not your enemy. Though, personally, we are far from friends.”

A person who probably isn't Pedro Karfski was encountered by the keymasters in their attempts to track Yadan-Ra, an off-putting and rude young man in a priest's vestments. Constance had some history with him, but little was known. Disturbingly, he appeared once more in the guise of a bartender, attempting to pry as to the opening of the Wave Echo Vault. Protophylarch's existence was concealed, even as he appeared to Percival in a dream (somewhat unwanted). He claims his interest in the Vaults is strictly academic, but is open about his lying and dissembling, and is seen as a nuisance at best and a threat at worst.
