Bruni

Bruni is a character in Disney's 2019 animated feature film Frozen II. A salamander of innocuous appearance, Bruni is an inhabitant of the Enchanted Forest and the elemental spirit of fire. Though shy at first, Bruni quickly bonds to those with the patience to understand him, as Elsa demonstrated. Bruni is one of four elemental spirits in the Enchanted Forest, the others being the Water Spirit the Nokk, the Earth Giants, and the Wind Spirit Gale. To the Northuldra, he is known as simply the Fire Spirit. When set loose, he sets the entire forest ablaze, creating beautiful but violent fires all throughout his path. But when in a passive state, he can create small flickers of flame to help the Northuldra tribe. Thirty-four years before the events of the film, the then-monarch of Arendelle, King Runeard, secretly murdered the leader of the Northuldra while their respective followers were celebrating their alliance together in the forest. Following his treacherous deed, Runeard instigated a war against the Northuldra to cover his tracks. Bruni, along with the other spirits, was so consumed with rage by the fighting that they turned against all the humans. A curse of a mist was placed over the Enchanted Forest and trapped everyone involved in the fight within it, and the elementals entered dormancy. The only way to undo the curse and sate the spirits was to destroy Runeard's dam—the object that sparked the conflict.
