In January 2553, his brother, Relon, had decided to destroy a Forerunner monument on his farmland. The Servants of Abiding Truth saw this as blasphemy, and soon attacked and destroyed Relon's keep with a Spirit. Jalam and Relon were both killed, and their corpses were heavily mutilated as a warning to others. Kaidon Levu 'Mdama ordered his aide, Thun, to cut down their bodies and cover them up.
