Cephalon
A being in which a human consciousness or a designed personality is turned into digital function, often as an Orokin punishment.
DIGITAL MINDFULL SPOILERS
Glassing and punishment
The Orokin could separate minds from bodies and bind them to a role of service. Memory wiping and personality editing can make Cephalon existence a prison as much as an immortality.
Personality and will
Programmed duties do not abolish a real personality. Ordis's Ordan Karris echoes and Cy's grief for a lost crew show the emotional continuity of a digital mind.
The variety of Cephalons
Simaris preserves knowledge, Suda holds music and curiosity, Cy commands a warship. It is wrong to count them all as one moral or political faction.
