The Lamp's mainframe completed my decryption job after priority computations about metaliminal storm predictions finished. It did not take long to break the primitive cypher.
It is indeed a full fledged colony mission that they were preparing.
Cryosleep pods are listed in several classes. The manifest contains a few very expensive ones that basically serve also as a medbay, probably for their "prophet" and his family. Then 1858 regular ones, I guess the mainline colony members. Livestock ones for cattle... and three thousand small cryojars, for human heads!? Why did their bring heads - surely not with the idea to revive them? Infomorph scanning and restoring were not available then. My guess is that it was for some blood ritual, part of their heresy.
The cryoship must have been large, for such a big group of people. It had energy and spares to last them well over sixty years in space, and six months supplies to get them started when they would reach their destination. The bulk of the cargo is machinery, building blocks, vehicles, and habitat prefab modules. They also have containers with cult objects, among them one that they must have cherished, the "Globe of Destruction". I have not yet heard of that relic, and will have to look up possible matches.
They are tables with navigational data. Those I will try to use to see to where they were headed.
