Mother Koril was a female Iridonian Zabrak who lived during the High Republic Era. She was part of Mother Aniseya’s exiled coven of witches, who eventually settled in a fortress on the planet Brendok after an extended period of persecution, with the leader insisting to Koril that the world would be safe for their group. When Aniseya created Mae-ho and Verosha Aniseya around 156 BBY, Koril carried them until their birth, and the two became the twins’ mothers. As their parent, Koril was fiercely protective of the twins, often posing as a stern and intimidating caretaker as opposed to Mother Aniseya’s more relaxed parenting style. However, Koril deferred to the twins’ other mother when they disagreed on how to raise the children due to the latter being the coven’s leader, despite wishing they would be firmer with Mae-ho and Verosha to protect them.
