The Cejansiji people originated from the planet known as Cejansij. They held their engineering abilities in high regard. One notable example of their civil engineering prowess was the Canyonade, a city constructed within a canyon across multiple levels, featuring various parks, meditation gardens, and skyarches.
Furthermore, the Cejansiji maintained a custom of non-violent political demonstrations. Luke Skywalker and Moshene Tre, a New Republic Observer from the Rellarin, observed one of these demonstrations during the Caamas Document situation in 19 ABY. This particular protest served as a remembrance for many of the galaxy's victimized populations, including the Caamasi and the Vrassh.
