The Eulogist
The AI's name for the engine that runs the centre system — the stable, personality-less intelligence the mantises mistake for a primal engine and the Nebulars worship — which the eighth floor's system AI lets slip in a boss description: 'one step closer to replicating the Eulogist, even though they don't know what that really is.' The epilogue's residuals part with 'May the Eulogist ever sleep.'

Progression
Donut's personal-space arena is called Arena of the Eulogist or something like that (ch. 9); in a hydra's description the AI lets slip that the mantises are one step closer to replicating the Eulogist without knowing what it is, mistaking the centre system's engine for a stable primal engine (ch. 46); Mordecai on the inner system's AI, 'the only one like it' (ch. 64); Agatha's feed signs off 'May the Eulogist ever sleep' — a universe swept clean so it can sleep (epilogue).
