The Univer functioned as a form of currency within the Unknown Regions. During 19 BBY, Che'ri, a sky-walker navigator of the Chiss species, along with her Caregiver, Mitth'ali'astov (whose core name was "Thalias"), were taken prisoner by Yiv, a General of the Nikardun. This general communicated with the Syndicure, the governing body of the Chiss, demanding a ransom of two hundred thousand Univers for their safe return. However, the Chiss managed to rescue the two women without having to fulfill the ransom payment.
In 18 BBY, Xodlak'ji'iprip ("Lakjiip"), a Senior Aide from the Xodlak family, remarked to Xodlak'uvi'vil ("Lakuviv"), a Councilor, that providing an artist with one hundred Univers for materials could result in the creation of a painting that could be sold for thousands.
The Univer was initially introduced in Thrawn Ascendancy: Chaos Rising, a 2020 novel, which is the first book in Star Wars: The Ascendancy Trilogy by Timothy Zahn.
