Ser Thornst is a [Spring Knight] of the Order of Seasons.
He is a veteran [Spring Knight]. He knows the value of diplomacy, and is good with horses. 
He arrived in Riverfarm through the grand ritual together with 28 other [Knights], led by Ser Raim. Nine Seasonal [Knights] perished, but the rest of them left Riverfarm directly after Belavierr won the fight, since back in Terandria, [Knight Commander] Calirn didn't wish to declare Belavierr an enemy of the Order.
