Jolla was a male Datugad native individual who lived on the planet Datugad in the 23rd century. After Datugad's inhabitants were poisoned by chemical contamination from their own mining processes, Jolla was one of the many inhabitants of that world infected by a chemical reaction causing spontaneous combustion.
In 2287, Jolla saw a familiar face in the crowds of quarantined inhabitants, a female of his acquaintance named Drambah. The two rushed to embrace, against the warnings of onlookers. They shared a few tender words of their need for each other before the chemical reaction caused by their proximity flashed with released heat energy, reducing the pair to ashes.
