In the year 3 ABY, Han Solo underwent a freezing process, encased within a carbonite block that subsequently gained the nickname Hansicle. This encasement was orchestrated by Darth Vader as an experimental procedure utilizing Cloud City's rudimentary Class-3 CFC, after which Solo's carbonite figure was handed over to Boba Fett for transport to Jabba Desilijic Tiure. The following year, in 4 ABY, Leia Organa, under the guise of Boushh, successfully freed Solo from his carbonite imprisonment.
