A wide grin split the boy's sun-freckled face. It was hard sometime to remember that he was actually of age, much less the lord of a house, however small, but still young enough to take great pride in every step that he made on his own.
– Torisen's narration, Bound in Blood, "Chapter IX: Scrying Glass"
Hollens, Lord Danior of Shadow Rock, is the current head of the Danior. He is distant or bone kin to Torisen, and is thus, at the time of Dark of the Moon, Tori's heir presumptive. Torisen often refers to him as Cousin Holly.
In Dark of the Moon, Hollens greets Tori at Gothregor, and formally welcomes him which starts a spontaneous and enthusiastic greetings by most Kencyr there. Later, after a battle with the Changers, Tori entrusts Hollens to retrieve the Kin-slayer and Pereden. In dealing with the latter in particular, Hollens proves his loyalty and intelligence. Jame met him after the Battle of the Cataracts. She thought he was nice, but too much in awe of Torisen.
Hollens is young. He has been lord for at least less that 15 years (the "old lord Danior" was lord when Tarn and Torvo were born) and likely significantly less than that.

↑Honor's Paradox, "Chapter V: The High Council", III — "A little boy, perhaps four years old, pelted shrieking between them, pursued by a harried Kendar. 'Danior’s son and heir,' said Rue wisely. […] Danior’s little son made almost everyone smile as he dashed up in his red coat crying, 'Cousin Tori! Cousin Tori!' "
