Bayrn, the young child with the Force, and his mother Ailish are Tarlafars, the hamster-like species first seen during the Sabacc game at Fort Ypso on the planet Vandor in Solo: A Star Wars Story (2018). Bayrn carries a plush toy based on his own species. Also visible in his home are plush toys based on a Gran and a Talz.
The Imperial orbital space station is based on concept art created by Ralph McQuarrie for Star Wars: Episode VI - Return of the Jedi (1983).
