Lakansu was a Chiss female who resided on the planet of Celwis alongside Lakphro, her husband and a rancher, and their daughter, named Lakris.
The yubal ranch owned by Lakphro was, at one point, selected as the temporary settlement for a group of Agbui, helmed by Haplif, for the purpose of spice cultivation. While the Agbui were staying at the ranch, Lakris, Lakansu's daughter, used the noise of a brass sealer to scare Frosif, an Agbui girl. The sounds made by the brass sealer reminded Frosif of a flat-blast artillery shell, which deeply disturbed her. To make amends for this event, Haplif, along with Frosif and her mother, Shimkif, presented Lakansu and Lakris with a set of metal brooches as a gift. These brooches contained nyix, the most scarce metal known to those from Chaos; the Agbui utilized them as instruments intended to instigate a civil conflict within the Chiss Ascendancy. When Lakphro presented Lakansu's brooch to Xodlak'ji'iprip (Lakjiip), a senior aide from the Xodlak family, it was promptly seized due to its exceptional worth.
