As the white whale left the Ice Blue system, Han Sen guided it towards where Night River King had been stationed. He was unable to find anything out of the ordinary there, however, and he couldn't find a single trace of that weird purple stuff that Night River King had mentioned repeatedly.
Han Sen even went to see the Ice Blue Knight who had taken over Night River King's position, but the knight hadn't seen anything strange during his time stationed there.
"Weird. What was that purple thing Night River King was talking about? What about the journal entries he made in code?" Han Sen didn't understand, but he didn't plan on lingering in the system to figure it out, either.
