Role Throughout Trilogy Edit
Arin is a Herrani slave who is a prominent member for the Herrani revolutionaries. He and Kestrel are engaged in a romance that frequently faces trouble throughout the trilogy.
The Winner's Curse Edit
Arin is first seen at a slave auction by Kestrel. She eventually buys him after hearing of his singing talent, though she never does hear him sing until much later on. He works as a blacksmith at the villa and collects information to feed to the Herrani revolutionaries. He eventually falls in love with Kestrel which makes him feel conflicted towards where his true loyalties lie.
The Winner's Crime Edit
Arin remains in love with Kestrel (albeit slightly bitter), despite thinking that she brought the military to fight the Herrani. He goes to the capital to confront Kestrel about her engagement to the prince and frequently corners her, although she continues to lie to him. He leaves the capital after hearing that Kestrel ordered the poisoning of the easterner horses, which ended in the mass killing of many of them. He heads east to make allies against the Valorian. He returns to the capital after finding out that she has been a spy for the Herrani from inside the capital but after she denies it he leaves again for Herran.
The Winner's Kiss Edit
Physical description Edit
He has light brown hair that is known to be long at the beginning of the first book, but that Kestrel will order to be cut. His skin is bronzed from outdoor labor and he is muscular. His eyes are stubborn but valiant (and the color is grey). He is also described to be very handsome.
Arin has had a very hard childhood. Even though he was slave for ten years, he kept a stubborn and arrogant attitude. He is shown to be quite honest. He is also shown to be selfless and to care deeply for his love ones (for example, he was very worried that Kestrel would try to kill herself after the Herrani rebellion, so he made sure that she wouldn't have any access to knives or anything of the sort.)
He is shown to be a good leader, and to be very smart.
