Harn was a cadet at Tentir during his father's—the Knorth senior randon—year as Commandant of Tentir. People made fun of Harn a lot, though Sheth was his best friend. During that year, Hallik took the White Knife.
Harn served in the Southern Host as a cadet. He was friends with Ashe, and she would guard his back during berserker rage.
After he became a randon, he worked his way up in the Host, serving as a one-hundred commander with Ashe.
Harn became a close friend of Torisen's. When Torisen became Commander of the Host, Harn was his second-in-command.
When Torisen became Highlord, Harn was bound back to the Knorth. He became the Knorth senior randon like his father before him, serving on the Randon Council.
During Jame's year at Tentir, Harn was serving there. After he has trouble, being drugged with Black forget-me-not and forced to relive his father's death by Graykin, possessed by the Lordan's Coat. After that, Torisen posts him in Kothifir, thinking it would be a good idea to get him out of there for a while. There in Kothifir, Harn finally becomes the Commander of the Host himself in The Sea of Time.
↑ 1.01.1The Sea of Time, "Chapter V: An Unexpected Guest", I — " 'Rather, pity those who went to other houses or who became Caineron yondri-gon like Harn Grip-hard.' "
↑ 2.02.12.2The Sea of Time, "Chapter XIII: Dreams and Nightmares", I — "Look how [the Caineron] had dealt with a senior randon like Harn, only a threshold dweller after all these years."
↑ 3.03.13.2Dark of the Moon, "Chapter 4: First Blood" — " 'Ashe and I were cadets and one-hundred captains together with the Southern Host long before you were born,' he said to Torisen."
↑ 4.04.14.2Dark of the Moon, "Chapter 10: The Lurking Past" — "She wondered where Harn was. In their days together, first as cadets and then as one-hundred commanders, she had always covered his back, knowing that he forgot it when the berserker rage seized him."
↑ 5.05.1Dark of the Moon, "Chapter 4: First Blood" — " 'Harn was second-in-command when I led the Southern Host,' he said levelly. 'Years before that, he was my immediate superior, when I was a one-hundred captain at the battle of Urakarn.' "
↑ 6.06.1The Sea of Time, "Chapter II: A Willow Rampant" — "Harn was second-in-command of the Host under the Caineron Genjar,"
↑Bound in Blood, "Chapter XVII: The Winter War", VII — "No one had been making fun of him for once and his best friend Sheth hadn't made one of his witty remarks—the sort whose sting is only felt afterward. Sheth probably didn't even intend to make him feel stupid. Perhaps smart people didn't understand how barbed their intelligence was to those less gifted. Besides, the boy's father was the current commandant of Tentir. Wasn't that a special thing, one to be proud of? And Harn was very proud of his father."
↑Honor's Paradox, "Chapter IV: Relics" — "Torisen wondered if Harn had yet reached Kothifir. After the randon’s rough time at Tentir that fall, it had seemed best to post him as far away from the college as possible for the time being, even though the one at fault had been his sister’s Southron servant Graykin, apparently possessed by Greshan in the form of the Lordan’s Coat."
