Eunuchs were not just palace servants — they were a deliberate tool for preventing the bureaucracy from capturing the emperor. With no family ties, no dynastic ambitions, and no network of aristocratic allies, they were entirely dependent on imperial favor. Emperors could place a palace eunuch in command of an army specifically to shake up established military networks. Sometimes, like Narses who defeated the Goths in Italy as a tiny old man, they were extraordinary at it.
