Trobert is a Black Arm Gang contact players must meet during the Heroes' Quest. He resides in a house east of Brimhaven, which can only be entered if the player gives him the correct password (four-leaf-clover). Only members of the Black Arm Gang can do this. When inside, the player receives some ID papers from him in order to enter the Black Arm Gang's building north-west of there.
After the quest, the player can no longer talk to Trobert, being given the message "He doesn't seem interested in talking to you." upon attempting to speak with him.
- Trobert's sword uses an older model of the steel longsword.
