Valsak was the High Captain of the Dark Brother's army. He led the siege against Lerellim and oversaw the death of the High King, allowing the Dark Brother to rule the known world. Although fiercely devoted to the Dark Brother, in the period immediately after the Dark Brother's victory, Valsak seemed to grow more lenient in his handling of the Dark Brother and his enemies. He prevented a group of raiders from slaughtering a farmer and burning his land immediately after the siege of Lerellim. While he did so on the grounds that the army would make use of the food the farmer grew, his lieutenant, Gersner, saw this as a weakness.
