Scotty

Scotty is a cleaner non-player character found in the Death Guard's headquarters, while doing Within the Light. He appears to be wearing mourner gear to protect himself from the plague, but when talking to him, he reveals himself to be just a cleaner man.

Trivia

 * According to Sanchez, he and Scotty formed a group known as the S&S Cleaners and used to work for Mandrith, who paid them 76,000 coins per hour. This is obviously meant to be a joke by Jagex, as a reference to the well-known PvP trick known as '76king', which used drop tables in PvP as a method of money-making.
