You arrive at Issica at 9pm. The city is a large, walled trading city built on the two banks of the Graywater. Merchants from all over come to do business, trading all manners of goods for the precious metals mined at Kaled Del, as well as trading with each other.
Other than the caravan stockade at the northern edge of the city, there are few roads in Issica. Most of the city is a network of canals, and it is hard do find a Issican who does not own a boat or at least a raft. Foot traffic is facilitated with a spiderweb of walkways and bridges. At night, the Lamplighter guild illuminates the canals with a network of Elvish beacons, and the city is bustling at all hours.
The population of the city is mostly human, but races from all over the Nine Moons can be found here. Dwarves make up a visible minority. They are mostly Stonelost Dwarves that found it easier to find work in Issica, but there are also dangerous exiles and fugitives that sometimes give Dwarves a bad name here.
Issica is also relatively lawless. The Moneylender Guild functions as the closest thing to an organized government, and it only concerns itself with making sure Issica remains a lucrative place to do business. Although the Moneylenders employ a mercenary company to patrol the city (the Hundred Swords), they are corrupt and anyone can buy their way out of trouble with enough gold. Peace is mostly kept in Issica because nations do not want to impede the flow of gold from this city and harshly police their own.
Guildleader Prust does the talking as you pass through security at the east rivergate. From there you are free to travel into the city as you wish. Some places of note to investigate:
The Barge Wright Inn is a comfortable, well-known inn that is owned by Dwarves loyal to Kaled Del. It is your meeting place for reuniting with Torden and a good place to talk to locals.
The Loremaster Guild religiously tracks the major events of the city going back many centuries. It is well known that their official publication of events is heavily censored by the Moneylenders, but they might have records that closer resemble the actual events that transpired.
The Temple of All Faiths advertises itself as a place of serenity and peace amidst all the coin and corruption. Worshipers from all faiths are welcome and they provide spellcasting and other religious services (for a steep fee).
The Warehouse District is the center of organized crime. It is rumoured you can buy the more rare and exotic things in the world there for the right price, no questions asked.
The Bazaar is open every day from dusk till dawn. Stock up on any items you want; prices are twice what are listed in the PHB.
The Constabulary is where you can contact the Hundred Swords.
