Dareon

Dareon is a background character in the first season. He is played by an unidentified extra and only appears in "You Win or You Die." He is a newly made Steward of the Night's Watch, of the same group of recruits as Jon Snow.

Season 1
Dareon is present during the speech Lord Commander Jeor Mormont gave to the "graduating" recruits. Dareon was assigned to the Stewards and Maester Aemon sent him to Eastwatch-by-the-Sea.

In the books
In the Song of Ice and Fire novels, Dareon is an apprentice singer from the Reach, sent to the Wall after being caught in bed with a daughter of Lord Mathis Rowan. Even though Dareon mantains that she was waiting for him naked and helped him into her room, she named it rape under her father's eye.

He's also an excellent singer, known to sign for the Watch during dinners; Maester Aemon describes his voice as "honey poured over thunder." Jon describes him as "quick but afraid of being hit."
