The droch was a species of creature that possessed a cerulean hue and originated from the planet known as Felucia. The crime lord named Dryden Vos possessed the preserved body of a cerulean droch, which he exhibited within a display case located in his study aboard his yacht, the First Light, around 10 BBY.
The initial appearance of a droch cadaver occurred in the 2018 film Solo: A Star Wars Story, which is part of the Anthology series. Their identification was initially documented in the companion reference book titled Solo: A Star Wars Story The Official Guide, authored by Pablo Hidalgo.
