Hest is a member of a wealthy Trader family. He is well-known for his outrageous parties where he travels cities with a pack of other men. He demands the best of food, drink and pleasures without thought to cost.
Hest is good-looking and charming, but selfish, manipulative, and cruel. He is secretly involved in a long-term relationship with his secretary Sedric Meldar.
After his father threatens to transfer Hest's inheritance to his cousin, Hest begrudgingly considers marrying. Sedric suggests his friend, Alise Kincarron, as a potential wife: she will be easy to court, as she has no other marriage prospects, and she is independent and will likely not interfere with Hest's lifestyle. Hest charms Alise and manages to convince her to marry him, although he only wins her acceptance of his proposal by admitting that their marriage is one of convenience for both parties. Hest ignores Sedric's dismay at his impending engagement.
Cruel and domineering, Hest willingly manipulates the emotions of others for fun and profit. Sedric recalls many occasions when Hest would 'freeze' someone out of social circles as punishment or as a game. Prone to foul moods, Hest takes out his black temper on others with unkind words and insults. Occasionally giving in to physical violence, he favors more subtle means such as nearly leaving Sedric in a foreign port or demanding he do unpleasant tasks.
His poor relationship with his wife culminates with her demanding to go to The Rain Wilds as stipulated in their marriage contract. Forced into it, he sends Sedric with her as a convulted punishment and carries on with his trading business.
He is both glad to see his wife gone on the Tarman Expedition but furious that she made a mockery of him in doing so. Later this turns to greed as Alise's part in the discovery of Kelsingra would grant her a 1/24th share of the profits. He also hopes to push a succesful claim that Sedric was representing his interests as his employee to provide him with a full 1/12th. Nevertheless he was rejected by both Alise and Sedric. He attempted to seduce Davvie, also to poor result. After being slapped first by Davvie and then by Sedric, he wandered to dragon baths where he met Kalo. Being full of himself as usual, he tried to take control of the dragon, who had other plans for him. He met his demise as dragon meal.
