Frost is a horse in Skyrim that appears outside Black-Briar Lodge during the quest "Promises to Keep." When completing the quest, the Dragonborn can persuade Louis Letrush to give up the horse, along with the second half of the payment. Alternatively, one has the option to kill Louis, granting ownership of Frost automatically. Frost seems to be more aggressive in combat than other horses. He has more health and stamina than regular horses, but less than the Dark Brotherhood's Shadowmere.
