Kolton was a Mahjarrat brought to Gielinor from Freneskae by the Menaphite god Icthlarin to combat the forces of Zaros. Kolton was at one time given the rank of Tribunus, the lieutenant to a Legatus in the Zarosian army. However, he was also part of the Inquisition. Kolton was partnered with the inquisitor Aurelius, assisting him with his duties in the Second Age until his mind was destroyed by Vos. The damage to Kolton's mind made him the ideal candidate for sacrifice at the next Ritual of Rejuvenation, and he was eventually sacrificed at either the 3rd or 4th one in approximately the years 919 or 1419 of the Second Age. This in turn also protected Sliske from being chosen as a sacrifice for the next few centuries.

- ^ Inquisitor's Memoirs (page 1), written by Aurelius, RuneScape. "Kolton was a Tribunus, yes - a soldier in the grand Zarosian Army. But he was also one of us. He was a member of the Inquisition, faithful and devoted to the one true god, Zaros."
- ^ Inquisitior's Memoirs (page 9), written by Aurelius, RuneScape. "His eyes were wide in equal parts wonder and horror and I felt the monolith reaching out to him, using the Shadow Realm as arms. In a flash, I saw the last vestige of sanity torn from his mind and he fell into a stupor on the floor, drooling like an animal."
- ^ Inquisitior's Memoirs (page 9), written by Aurelius, RuneScape. "Poor Kolton never regained control of his mind. It made him the perfect sacrifice for that cruel Mahjarrat ritual. Sliske had destroyed me and guaranteed his safety from the sacrifice for at least another few centuries."
