The Mark I is a Thieving dummy situated in the Thieves' Guild in Lumbridge. Players with a certain level in thieving will not receive any experience from this training device. After the caper A Guild of Our Own is completed a player can pickpocket the Mark I to teach Darren Lightfinger their skills and earn 2,000 thieving experience for doing so, one of the actions required for the Master quest cape.
- When pickpocketing the dummy, the player will receive comments or thieving tips such as "It's the eye of the Kyatt, it's the will of the heist", a reference to the Survivor song "Eye of the Tiger".
