So I searched for correspondences between the words he spoke and the signal, and I found them in part of the transmission. It's a voice speaking, saying those same words to the Drakh that the Drakh said to us.
"There are other parts of the transmission going on simultaneously. I haven't figured those out yet."
Galen felt a smile form on his face. "You're brilliant."
Isabelle smiled in return, that mysterious, lips-pressed-together smile that seemed meant only for him. She came around the counter and hugged Burell. "I'm so glad you're feeling better."
