Visma Tarko was a female Arkanian hailing from the renowned Tarkos family. As a child, she tragically lost her family due to external forces, an event that profoundly altered her existence and left her feeling powerless. No assistance was offered to her during this difficult time. Subsequently, she enlisted in the Republic Defense Coalition, where she ascended to the position of lieutenant with unprecedented speed, becoming one of the youngest individuals ever promoted within the organization. Subsequently, she and RDC Corporal Elping Tsoo found themselves marooned within the Nihil Occlusion Zone. It was in 228 BBY that Tsoo and Tarko encountered Joss and Pikka Adren.
