Part 1. The Harbour and parts of the Undercity.
Leongarde’s closest harbour lay before them.
They could see the sailors work quickly to set the fins and side sails back and tie them up as they sailed towards the underbelly of the city.
In order to reach the harbour they had to sail into the opening within the rock.
This would lead them to the harbour that lay within, in a large cavern that opened up and brought them to the underlayer of the city.
There it would dock and they would be able to step off.
The dark rough stone opened up for them and as they sailed into the opening swallowed them whole, floating on the current within and the smooth movement of the tail-fan sail, which gentle movements offered them a soft thrust, allowing them to glide in with care.
The place seemed dark, damp and cold, but was lit partially by Sinderdust that lined the walls with wonderous glowing veins, as if they entered a living breathing creature.
From afar they could discern a the hint of a gentle drum, continuous and repetitive, before other differently coloured lights filled the tunnel as it widened and showed the crystal roof above them, almost like a glass ceiling of sorts. Then the doors of Avelore doomed up out of the darkness.
Two massive stone slabs that opened before them, groaning, complaining as the mechanism that was involved was put to work again. From the side the could hear the cracking of a whip, beating some unfortunate as they sailed out of the cavern and into the open harbour before them. The docks stretching out around them, in a circle, giving access to the underlayer of the city and the stairs to the higher levels.
The Harbour and the undercity was very much that, dark grimy alleyways and streets made up out of miners and mist harvesters homes. The sailors, women of low repute and prize fighters would drop in on alehouses and seedy taverns. Other less professions that were very much needed, but weren’t allowed to be noticed were leather tanners, dyers, slave houses & houses of pleasure. 
Naturally there was a more refined part of the harbour, that’s where the rich went, it was named ‘the Pavilion’ and it was heavily guarded and very selective on who they allowed to enter. It also was run by the one of the most ruthless criminal groups to ‘serve’ the city.
If you looked further you could see young priests proselytised the mercy of the mother, being ignored by almost all whilst in an alleyway around the corner some cheeky little whore sucked the life out of a very content customer.
All in all the Harbour told anyone who paid attention that those living there were dealt a bad hand in life, theirs was a harsh life, where most of their earnings would be spend on forbidden pleasures and drink and it was clear by the few elderly moving about, that these people died young.
