Masked stranger

Masked stranger is an NPC involved in the 2017 Hallowe'en event. Six of them were found throughout Varrock, performing various actions, such as mining and making potions. These indicated to the player as to how to help the strangers, which was to brew a spectral potion, and use it on the stranger. Unfortunately, this resulted in the return of Jonas, a vengeful spirit described by the Grim Reaper as the "truest of all evil".

Trivia

 * The masked stranger was briefly added in a hidden update on 13 October 2017, and removed a day later on 14 October. He appeared in various locations, including Falador Park, Lumbridge Swamp, Barbarian Village, and Varrock west mine, and Etceteria. Rarely, the stranger's face would appear on the screen and laugh at the player, similar to Durial321 or the Barrows brothers.
