The Gatekeeper is a tree like figure who guards the gate to the Zanaris market area. He will only let players pass if he is paid the trade tax, which is one cut diamond. He says that the diamond is used to make fairy lights. He guards the dragon dagger and dragon longsword shop, and the gem market.
He says the gatekeeper that was there before the Zanaris update was his father. When asked about this, he replies "I got my good looks from my mother."
- Mod Biscuits stated on the Official Runescape Forums that "The Gatekeepers were originally referred to as Mindslayers by the original developer of the fairy storyline. We still sometimes refer to them as Mindslayers even now. It's just an internal name we use for the Gatekeepers.".
