Jyrom Ottdell held the rank of admiral within the Imperial Navy and Imperial Officer Corps of the Galactic Empire. His life came to an end in 1 BBY when he was murdered via poisonous zolall extract, prompting Agent Andressa Divo to launch an inquiry into the Malkite poisoners. During this investigation, Divo placed orders for multiple "Malkite poisoner kits" via the HoloNet; only one proved genuine, bearing an inscription that cautioned the agent to cease her investigation.
The character Jyrom Ottdell was initially referenced in Star Wars: Scum and Villainy: Case Files on the Galaxy's Most Notorious, a reference book from 2018 authored by Pablo Hidalgo.
