Silri was a powerful Nightsister, a dark side witch of Dathomir. She worked for Tyber Zann and his criminal syndicate, the Zann Consortium, in the time following the Battle of Yavin in the hopes of being able to witness and partake in the destruction that Zann intended on causing. In combat, she used dark side powers, such as Drain Life, and also a lightwhip, an exotic variant of the traditional lightsaber. Silri also had a pet rancor, Cuddles, that she could summon during battle.
