In the past, players had to speak to him to gain a test paper. Left-clicking on the test paper, answering the multiple-choice questions and handing back the papers completed the miniquest. Professor Henry then rewarded the players with two antique lamps (which each give 500 experience in any skill). Passing the test also allowed players access to the Stronghold of Player Safety dungeon, and gave a new emote called "Safety first".
Nowadays, both antique lamps and the emote can be collected from the same vault as the safety gloves beneath the jail beside the Training Centre.
- The character most likely was based on Dr. Henry Jones Sr, as played by Sean Connery in the 1989 movie Indiana Jones and the Last Crusade.
- If you examine Henry's satchel near the door of the classroom, It states: "Professor Henry's Satchel. There's some sort of cup in here.". Continuing the theme, it is most likely referencing the Holy Grail that he and Indiana Jones have to retrieve in Indiana Jones and the Last Crusade.
