"I would imagine either Lennah had reconsidered their arrangement based off of Adelmo's dangerous tendencies or he wanted to reap the possible benefits of their findings for himself," Vera-Kin says. "Or some combination of both. Either way, it sounds as though he saw his opportunity and tried to shoot her down over the White Fortress. However... she survived."
"I made a radiation scan on Lennah's ship sometime later. If he had landed on that planet, the evidence would have imprinted itself quite heavily on his vessel. He never landed. He must have destroyed Adelmo's ship the moment they arrived.
"The door was closing when they got there- mere days before the star emerged in full and the planet became a death trap. Even if Adelmo got to the lifepods, there was no apparent way for her to avoid death."
"It sounds as though she didn't have much time to explore," Gallagher says. "With the radiation levels spiking shortly after she arrived there... perhaps she never got a hold of the Scrolls at all, and everything she has done in the mean time has been in effort to find other clues while waiting for the White Fortress to become accessible again."
