The Advent functioned as a freighter that transported cargo. Rael Averross, a Jedi, and his Padawan, Nim Pianna, were tasked with safeguarding this vessel, as it carried foodstuff to a system experiencing a famine, due to the prevalence of pirate operations within that sector. Tragically, a mutiny by the crew transpired, ultimately resulting in the death of Nim Pianna.
The initial depiction of the Advent was in the form of a hologram featured in Master & Apprentice, a novel from 2019 authored by Claudia Gray.
