After Jan and his colleagues are arrested and escape, with their official investigation shut down, they head to the Veritas Hideout and meet Alexei. Alexei says he could use people like them on his side. He allows them to remain at the hideout until things cooldown. Alexei tells them about Yuriev being able to put a lot of pressure on the sixth division of the Federation Police as well as the fact that Sergius XIV will be leading the upcoming Pilgrimage Council. He also tells them what he knows about Voyager, whom he calls the Net Preacher and says there have been a lot of copycat crimes.

After Jan's death, Alexei takes in Melisse as a member of the organization, until she splits off to form her own organization, Scientia.
