Obsidian Cliff was a city in the sense it had a lot of people, a market, and production area but compared to even the lowliest city in the world Lind had been to, including in the Dread Desert, it was bare bones. There was thin Qi but the city worked as a collection and distribution point for the crops from the outlying villages.
It made Lind angry to see the vast warehouses holding the weakened crops handed out to the commoners but as he moved closer to a more robust building carved into the cliff face, the food quality jumped much higher.
Lind recognized some of the very birds he hunted being fried openly but only peak Soul realms to some Sand Tiers could afford the prices he saw. It demonstrated the state of the Kingdom of Altair.
