Some more background to help you flesh out your characters:

So the scourge began invading around a year ago, each character has made their way to the city if they weren't there already. They had enough renown to be looked to for leadership and they've been spending most of the past six months preparing the 150 ship fleet for escape and building up their defenses. Needless to say the general emotions of the city are rooted in tension and fear

Trade has obviously stopped for the most part. Some aristocrats still think they can buy their way into a better position, but nobody else seems to care much about money at the moment.

Many traditionalists blame recent technological advances for either attracting the scourge or incurring the gods' wrath to send the scourge upon civilization. Felix has been the most successful and influential priest, and the society has a strong leaning towards Torag, though all the gods typically found in a city are still being worshiped and followed. Agatha, Haruki's character, also lowkey has a cult following.

The bastion is divided such that the slums are a long, narrow stretch that borders the wall. The most minority races (gnomes, half-elves, half-orcs, orcs, tieflings, kobolds, catfolk, ratfolk, and tengu) live in the slums, alongside a sizeable number of the halfling population.

There is a dwarven quarter where one end of the wall meets the water, and an elven quarter where the other end meets the water. The docks were bought out by the wealthy as soon as they heard the plan to evacuate. The rest of the city, mostly humans and halflings, live in the center.

The dwarves are represented by Gammar, a war hero and leader who had the foresight to move his people to the Bastion before the Xill could kill most of them.

The elves are represented by a council. Though most of them keep to themselves, Lorekeeper Ayrie, and occasionally Llenasae, act as ambassadors between the city's leaders and the council.

If the slums have any representation, it's through The Compelling Savages. This organization is considered criminal, however, so they don't communicate directly with any leaders.
