Chapter 9
Aether
Aether is the greyhound spirit of motion, messages, shortcuts, and urgent direction.
Aether arrives before anyone officially hires him: already answering phones, guiding guests, and leaving paperwork behind.
The House accepts him because motion is part of how Nox survives. A message that arrives late can become a locked door.
His lore connects to Zephyrus and the First Shift because movement, chance, and staffing all decide whether the House responds in time.
