Vanzeist, a planet, was the location of a victory celebration held by the Rebel Alliance's 61st Mobile Infantry after a triumph over the Galactic Empire, occurring around 3 ABY. In that year, Prelate Verge of the Imperial Ruling Council assured Imperial Lieutenant Kourterel that a stormtrooper unit would be dispatched to Vanzeist to safeguard his family from Alliance members. First Sergeant Hazram Namir later recalled the celebration on this world in 3 ABY, as he reminisced about events within the 61st during the funeral service for the company's deceased captain, Micha Evon.
The 2015 novel Battlefront: Twilight Company by Alexander Freed included a reference to Vanzeist.
