This is a quick one, but still worth noting. Recently, the fine people of Critical Role aired a one-shot Call of Cthulhu game featuring regular cast members and special guest players to indulge in Taliesin Jaffe's favorite past time - scaring the crap out of his friends. Based on the works of H.P. Lovecraft, the game is a love letter to pulp adventures, Victorian Gothic and horror literature, and psychological trauma.
In this particular one-shot, Call of Cthulhu: Shadow of the Crystal Palace, the players are tasked with retrieving an item for their wealthy American benefactor among the artifacts and exhibits within London's Crystal Palace. While the caper seems straight forward, the party has no clue what lurks in the shadows waiting to strike.
Within the party is one Dr. Mason Pocket played by Phil LaMarr. Dr. Pocket is the British Museum's Antiquities Archivist and his expertise comes in handy once the shadows - and the mirrors - start betraying the players. Not much goes into fleshing out what goes into his role as an archivist, but rest assured that Dr. Pocket makes some excellent History, Archeology, and Occult rolls that help the party early on.
"Does he survive?" you ask.
"That is an excellent question," I respond.
Maybe this will help: Dr. Pocket has a cat named Io.
