Only In Death Does Duty End
An immense being that was released from its prison by tech priests from Tithe Station Iota. It corrupted these tech priests by giving them information at a higher rate than they could handle, and made them build it a titan to use as its ride home. This titan was created by repurposing the interior of the Chalice arm of the station, as well as the 15.000 people living and working there.
The Cephalophore gave Maza a data crystal before escaping our galaxy. This crystal presumably contains the same information given to the tech priests of Iota, hopefully given at a rate that will not corrupt Maza.
