*Lilith and Roland returned to Pandora as Hyperion began its rise. Lilith's powers grew substantially from absorbing Eridium, the element released after the defeat of the Destroyer. She was one of the founding members of the Crimson Raiders to fight against Hyperion, along with Brick, Mordecai, and her then-boyfriend Roland.
During Hyperion's raid on New Haven she, along with Roland, Mordecai, and Brick, were defeated. With the city overrun and she presumed dead by Hyperion, they were forced to abandon New Haven for Sanctuary. Roland ended his relationship with Lilith in order to focus on Hyperion and the Crimson Raiders, while she drew Bloodshot bandits away from Sanctuary under the alias Firehawk.
After Roland was captured by the Bloodshots, she sent a message under her Firehawk alias telling the Vault Hunters to come to Frostburn Canyon. When they reached her base of operations, they discovered that Roland wasn't there and that Lilith was the Firehawk. After fighting off waves of psychos (with the power of "Phaseblast" that can pulverize enemies), Lilith returned to Sanctuary to lead the Raiders in Roland's absence. She remained there after Roland's rescue.
When Sanctuary became unshielded after Angel's treason, as Hyperion attacked Lilith doped herself with a large amount of Eridium to strengthen her powers. She was able to make the whole city enter Phasewalk with her. Sanctuary became the current flying city, safe from Hyperion for the moment. However, she had revealed that she was alive and working with the Crimson Raiders.*
