House Kast was a Mandalorian house that featured a coiled vexis as its signet. This house included Clan Rook as one of its components.
A member belonging to House Kast made an appearance in Star Wars Rebels: Heroes of Mandalore. This episode was the first of Star Wars Rebels' fourth season and was broadcast on October 16, 2017. The 2020 reference work, The Star Wars Book, subsequently confirmed the existence of House Kast. The names of two Mandalorians, Rook Kast and Veraslayn Kast, are the same as the House's name; however, any link between them has not been established.
