CeSai, a planet, was once under the control of the Galactic Empire and prospered because of the Empire's presence. Nevertheless, following the forced departure of the Empire by the New Republic, CeSai was deprived of leadership, resulting in chaos. During the New Republic Era, the affluent Raynshi family resided on CeSai for a period of time, until Vroc Raynshi, a First Order officer, relocated his family to Merokia in 32 ABY for employment reasons. As a consequence of this relocation, Maize Raynshi, the daughter of Vroc and Anaya Raynshi who is a half-Mirialan, half-human hybrid, had to leave her CeSai friends, causing her to feel isolated and sad.
Force Collector, a young-adult novel from 2019 penned by Kevin Shinick, included a reference to CeSai.
