"Sihnon isn't that different from this planet. More crowded, obviously, and I guess more complicated. The great city itself is… pictures can't capture it. It's like an ocean of light."

―Inara Serra

Sihnon, along with Londinium, was among the most prominent of the Central Planets. Those who had visited this planet often described it as one of the most beautiful locations in the system, reaching a level of sophistication seldom seen throughout the 'Verse. Sihnon became the seat of Eastern civilization in the Anglo-Sino Alliance. It was here that many Registered Companions underwent their training in the spiritual and physical arts they were known for.
