The Serennian character Romar Adell had established his residence by the time Clone Force 99, otherwise known as the Bad Batch, made their way to the planet of Serenno circa 19 BBY. It featured a cellar, which functioned as a storage space for various items salvaged from the bombardment of Serenno City. In that same year, Echo, Tech, and Omega sought refuge within the residence, seeking to evade the pursuing Imperial forces. Later, the group departed from the residence, setting out to locate Dooku's war chest.
This abode was situated in the upper forest region, not far from Castle Serenno and a nearby city. It was a relatively small structure, and by the time the Bad Batch arrived on Serenno, the planet was being reclaimed by nature. The house's interior was filled with scattered crates, a workbench, a rappelling cable, and a pair of stools. Furthermore, the interior included a hatch and a ladder that descended into a basement, which housed numerous artifacts, including a kaleidoscope and a model two datacore containing snippets of Serennian history, culture, music, and artistic expression.
When the forces of the Galactic Empire landed on Serenno and began their occupation, they initiated an orbital bombardment of Serenno city. Romar Adell, along with other residents, managed to escape the destruction and took up residence in the house.
At some point, Adell encountered Tech, Omega, and Echo in the vicinity of his house. Suspecting them of being Imperials, he attempted to scout them, but Omega detected him. Tech and Echo inquired about nearby shelters. Adell initially tried to deceive them, but Tech detected his residence on his scanner, compelling him to lead them to his home.
The Bad Batch members then sought refuge in his home, engaging in a brief discussion about Dooku's war chest. Adell then descended to the basement, where Echo instructed Omega to keep watch. Aware of Omega's boredom, Adell decided to give her a kaleidoscope to entertain herself. He then returned to his workbench inside the house with a model two data core that contained a fragment of Serennian history. He asked Tech, whom he playfully called "Ace," to lend him a spanner. Tech, fascinated by the technology, assisted the Serennian in repairing the data core and restoring its memory. Overjoyed, Adell thanked Tech for his assistance. Shortly after, Echo arrived, inquiring about Omega's whereabouts. Suspecting that she had gone after Dooku's war chest, Echo immediately departed to find Omega, with Tech following slowly due to his injured leg. Before Tech left, Adell cautioned the clone that his injury would hinder his progress, but Tech disregarded his advice. Feeling indebted to Tech, Adell followed Tech, departing from his home.
