The three of them help Duke Martin prepare for the attack by poisoning moredhel food supplies, finding the minstrel Tamney, stealing the moredhel battle plans, and killing six moredhel magicians hiding behind Kingdom lines.

James and Locklear arrive at Northwarden and are sent by Baron Gabot to find his magical adviser Patrus. Learning of the impending attack on Northwarden, Arutha readies his army and sends Owyn and Gorath to Krondor to seek Pug's help in case the moredhel employ magic. They escape Sar-Sargoth and head south to the Inclindel Gap, where they meet a Kingdom patrol and are taken to Arutha's camp. Narab turns on Delekhan and, unbeknownst to them, frees Owyn and Gorath. Delekhan, enraged that Narab has ruined his plans, tells him his life is forfeit. Gorath and Owyn are taken to Sar-Sargoth, where Narab presents them to Delekhan. Before they can reach Arutha though, Owyn and Gorath are captured by Narab, one of Delekhan's chieftains. James heads to Northwarden while Owyn and Gorath head south to warn Arutha. Realizing that Nighthawks probably infiltrated the fortress, they split up. After killing him, they enter the Nighthawks' hideout in the caverns beneath Cavall Keep, where they learn that Delekhan plans to attack Northwarden. James, Owyn, and Gorath follow the trail of the spyglass and the spider north to Cavall Keep and uncover the leader of the Nighthawks, the merchant Navon du Sandau. Two clues were left behind at the murder scene: an enchanted spyglass and a silver spider. Arriving at the tavern in Romney, they discover that the king's soldiers have all been murdered. James, Owyn, and Gorath secretly slip out of the city through the sewers and head east. Arutha will muster his army and await word of where the attack will occur. Arutha arranges for James to escort Gorath to Romney and meet with a group of the king's soldiers investigating recent Nighthawk activity in the east. Gorath thinks they can find out by intercepting Delekhan's Nighthawk spies in Romney. Gorath informs Arutha of Delekhan's plans, but Arutha does not trust him because he does not know the location of the attack.

Upon meeting Prince Arutha, another moredhel assassin sneaks in and attempts to kill Gorath, only to be foiled by Pug. Finding the palace gates sabotaged, they enter the palace via the sewers with Seigneur James' help. Surviving multiple assassination attempts, they eventually reach Krondor. Owyn is bandaging Gorath's and Locklear's injuries when they are attacked by a moredhel assassin whom Gorath dispatches before the three of them set out south. The game begins in their camp north of LaMut. Injured from numerous attacks, they ask for help from Owyn Beleforte, a young magician from Tiburn. Gorath has brought a warning of an invasion planned by Delekhan, leader of the moredhel, so Locklear agrees to take him to see Prince Arutha in Krondor. Ten years after A Darkness at Sethanon, Seigneur Locklear is serving at a northern Kingdom garrison when he saves Gorath of the Ardanien from an assassin.
