Kellan is approached by Echo in his cell. He informs her that Stahl plans to use Massar's bio-tech weapon to kill Vektans and half-breeds alike, including Echo (who is half-Vektan, half-Helghast). Echo, who is revealed to be Lady Hera Visari's daughter, is displeased with Visari for being in league with Stahl and planning to ignite another war. She helps Kellan escape his cell and returns him to the Vektan side of The Wall in order to convince the VSA to stand down. Upon his return, Sinclair ignores Kellan's pleas to stand down, outraged that he is siding with Echo. Instead, Sinclair informs him that the VSA have tracked Massar to a massive mining spire in orbit over the planet Helghan, and dispatches him to recover the doctor. Kellan infiltrates the main spire and finds Massar. She states that the bio-weapon is now with Stahl, being prepped for its final test. Sinclair orders Kellan to take Massar into custody, but Echo arrives and kills Massar as Kellan watches on. Now viewed as a traitor by Sinclair, Kellan teams up with Echo, and the two descend to Helghan to stop Stahl.
