Brother Malchus, Chief Acolyte within the Order of K'tau, is one of the religious leaders of the planet K'tau. He was highly antagonistic toward SG-1, insisting that they were harbingers of doom, especially when K'tau's sun inexplicably experienced a shift in the light spectrum toward infrared. SG-1 prepared to launch a rocket toward the planet's sun to correct the problem, but Malchus, who put his faith in Freyr and distrusted the visitors, orchestrated the sabotage of the rocket that killed two members of SG-6.
