Kristoff Bjorgman

Kristoff Bjorgman is a Sami ice harvester who, alongside his friend and reindeer, Sven, was raised by the trolls. He generally kept to himself and only interacted with other humans when necessary, preferring the company of Sven. As such, Kristoff only accompanied Anna on her quest to retrieve Elsa strictly as a business arrangement but would eventually develop feelings for the princess; to this end, he strove to ensure her safety as she worked to restore both summer and her bond with her estranged sister. After summer's return, Kristoff and Anna began a romantic relationship.

History Early life Kristoff and Sven hiding behind Bulda Kristoff and Sven were adopted by a female troll, Bulda. Kristoff grew up an orphan. At some point in his childhood, he rescued a fawn, Sven, and the two became friends.During his early years, Kristoff mostly accompanied the ice harvesters, working hard in spite of his age to earn his place amongst the grown men. One night when he was eight years old, Kristoff was following the other ice harvesters back to Arendelle on a small sled pulled by Sven. However, he noticed two horses and their riders rush past and was surprised when he saw that there was a trail of ice being left behind. Curious, Kristoff abandoned his sled and mounted Sven in the hopes of seeing where the trail of ice led; the two soon reached the Valley of the Living Rock.

Not wanting to be seen by the riders, Kristoff and Sven hid behind a series of rocks. As Kristoff watched the four figures, he was shocked to see some rocks move of their own accord towards the visitors, though he eventually realized that the rocks were in fact, trolls. To his surprise, the rock he and Sven had been hiding behind suddenly sprung to life; this female troll, Bulda, regarded Kristoff and Sven warmly, remarking that she would "keep" them. Afterwards, Kristoff watched as Pabbie healed a little girl with his magic.

True to her word, Bulda took in Kristoff and Sven, and Kristoff came to regard the trolls as his adopted family. During this time, Kristoff grew closer to Sven, going as far as simulating Sven's voice so that they could "converse".

Kristoff also has a degree of musical talent, capable of playing the lute and singing a lullaby to Sven.
