Kuma'tiki is Lunamor's second daughter. She is named after a type of shell found in the Horneater Peaks.
Kuma'tiki arrived at the Shattered Plains with her family in Jes 1174 after traveling for months to meet with Lunamor, who sent them a message shortly after his arrival. Kuma'tiki's caravan was attacked by Voidbringers and her family defended themselves behind a pile of furniture. During the attack a member of her family shot a Voidbringer with an Unkalaki arrow. They were found by Bridge Four during a patrol and taken to Urithiru. After settling in Urithiru, she helped her father serve food and drink to Bridge Four.
