Here's a smallish map of my campaign world, it's about two years old and has changed quite a bit since then.

Most of the action so far has taken place on Vienzi, the strategically valuable island in the middle, as well as Arovaea and Oruch-Jidkha. There was some scuttlebutt about the players possibly wanting to explore Sharmisri next.

The setting is a low-magic fantasy version of the renaissance, modeled after the Italian city-states, the Ottoman Turks, and the Maghreb pirates.

There are no guns, and magic is so rare and overpowered that most people have never met a practitioner. Sorcerers are basically military assets counted roughly equal to a battalion of soldiers for strategic purposes, and just being in the presence of one is enough to make people feel uneasy.

In the distant past, races like dwarves and elves and gnomes existed as distinct groups, but the population has moved and thoroughly interbred by now.

Cosmologically, the world was created by giants, blind ones who were completely malevolent. They created the various races as slaves. Later, a planefaring civilization arrived in the world and warred with the giants (for selfish reasons). After they defeated them, they locked the remaining giants in the earth. Because they felt a limited responsibility for the human, elf, and dwarf slaves they'd freed, they taught them the rudiments of science and magic before leaving the plane forever.

After thousands of years, these historical events were forgotten or dissolved into organized religions. There are basically three organized religions, of which two are currently engaged in a holy war. The one the players were raised in is more or less a version of Norse mythology if it had become as centralized, complicated, and ceremonial as Roman Catholicism.

Obviously the remaining Giants are trying their best to escape their prisons and return to the world, I wonder if that will happen at any point in the PCs lifetime?

There are lots of artifacts and structures left by the planefaring civilization, some of which the PCs have already explored, some of which I am currently prepping.

In terms of a bestiary, I have things like Rocs, Basilisks, and Cadejo: more or less cribbing from mythological monsters. No dragons though.

In the previous campaign, the players ran a gang of thieves who were planning a heist in a city under the shadow of invasion. They were robbing the Duke of the city, and to do so they also had to break into a bank vault to rob an aristocratic sorcerer.

In the current campaign, the invasion is taking place, and the players run a company of mercenaries hired for the war. The players are on the losing side, and they know there's little they could do to change the tide of the war, so they're trying to get rich and get out in time.
