Anna is the younger sister of Elsa, who is the Snow Queen, and the current ruler of Arendelle. As children, an accident involving Elsa's magic caused a rift between the sisters and left Anna without love for a long time. However, Anna remained kind and hopeful, despite being somewhat socially awkward. When the estrangement leads to an eternal winter, Anna embarks on a dangerous journey to save her kingdom and repair her relationship with her sister.
Bruni is one of four elemental spirits in the Enchanted Forest, along with the Water Spirit, the Nokk, the Earth Giants, and the Wind Spirit, Gale. The Northuldra call him the Fire Spirit. When unleashed, he can set the entire forest on fire, causing beautiful but destructive blazes throughout the area.
Elsa is the older sister of Anna and the former queen of Arendelle. She was born with the ability to control ice and snow. For most of her life, Elsa believed her powers were monstrous and isolated herself from others to protect her family and kingdom. However, her fears caused a curse that froze Arendelle in an eternal winter. With the help of Anna's love, Elsa learned to control her powers and gained self-confidence, allowing her to live peacefully among her people.
Gale is the first elemental spirit that Elsa, Anna, Kristoff, Sven, and Olaf encounter in the Enchanted Forest. She picks up Olaf in a tornado, scaring him badly, and then captures the others as well. Elsa is able to calm Gale, who transforms into a playful swirl of leaves, instead of a threatening tornado.
Pabbie is the king of the trolls and is likely the oldest member of the community. He has a mane like a lion, which sets him apart from the other trolls and symbolizes his leadership role. Pabbie also wears a green cloak made of moss.
Runeard was the king of Arendelle and the father of Agnarr. He was seen as a noble and generous leader, but in reality, he was a cruel and paranoid tyrant who saw magic as a threat to his rule. In an attempt to destroy the Northuldra, Runeard started a disaster that lasted for decades, and it was up to his granddaughters, Anna and Elsa, to fix it.
Kristoff is a Sami outdoorsman who worked as an ice harvester with his reindeer, Sven. He was raised by trolls in the mountains and initially distrustful of humans, but he began to change his views after meeting Princess Anna. By the end of their adventure, Kristoff falls in love with Anna and becomes engaged to her. He is also welcomed into the royal family of Arendelle.
The Northuldra are an indigenous group who live in the Enchanted Forest north of Arendelle. They are called the "people of the sun" and are not magical themselves, but they have a strong connection to the magic of the forest and its elemental spirits - the wind spirit, Gale, the fire spirit, Bruni, the water spirit, Nokk, and the Earth Giants. The Northuldra used to have a friendly relationship with the people of Arendelle, but a betrayal caused a conflict between the two groups, leading to a group from both being trapped in the forest for 34 years and cutting off all outside communication.
Oaken manages Wandering Oaken's Trading Post and Sauna. However, due to Elsa's winter storm in mid-July, he has an excess of summer supplies. He is generally helpful and good-natured, but if you cross him, he will not hesitate to throw you out of his store.
Sitron is a dun-colored Fjord horse with a round, sturdy build. He has a mane of black and off-white and resembles Anna's horse, which is a pale gray color with a white and black mane. Fjord horses are robust, but not as large as some draft breeds.
The Snowgies are created when Elsa sneezes. The more she sneezes, the more Snowgies appear. They go to the castle courtyard and cause trouble, particularly with Anna's birthday cake. Kristoff, Sven, and Olaf are able to control them before Anna and Elsa arrive, and the Snowgies even put on a show for Anna's birthday party. Afterwards, Kristoff, Sven, and Olaf take the Snowgies to live in the ice palace with Marshmallow.
The Spirits of the Enchanted Forest, also called the Elements, are five elemental beings that appear in the movie Frozen II. They are mythical creatures that control the magic of nature and include water, fire, wind, earth, and a fifth spirit that connects magic and humanity.
The trolls are generally loving and family-oriented, as shown when Bulda adopts Kristoff and Sven, and when the trolls try to convince Anna to marry Kristoff. They can also be a bit crude and intrusive, but their teasing is meant to be affectionate. They see Kristoff and Sven as part of their family and treat them accordingly.
