Hareth (Mole's Town)
Hareth is big, blond and has buck teeth.
A Storm of Swords
When wildlings attack Mole's Town and Castle Black, Hareth is one of the Moles who flee to the Wall. There he helps defend Castle Black. He declares his interest in joining the Night's Watch. He is trained by Jon Snow due to the loss of Ser Endrew Tarth as master-at-arms at Castle Black.
A Dance with Dragons
Horse is trained by Iron Emmett after his appointment as master-at-arms at Castle Black. Jon, the new Lord Commander of the Night's Watch, spies him training in the yard against Hop-Robin, whom he easily defeats. Jon compliments his skill, but advises him that he lowers his shield too far when pressing the attack. Horse thanks the Lord Commander for his advice as he helps Hop-Robin back to his feet.
Horse later travels to the weirwood grove just north of the Wall in the haunted forest to say his vows. He is accompanied by five other recruits (Leathers, Jax, Satin, Arron, and Emrick). They are escorted by Jon and ten rangers. Jon, Iron Emmett, and Bowen Marsh weigh each recruit and assign them to an order. Horse is assigned to the builders.
