The known world is formally called Celos, though only academics use this name. Following is a brief index of the most important islands, with a map provided overleaf.

Aaru. This desert island was once fertile and home to a mighty empire dominated by the reptilian bakrog. It was destroyed long again during the Runewar, which was waged against the jotunkin and the Drakewardens of Myrr.

Burning Isles. These used to be a single island called Usterlay, which was home of the Jotunkin. But it sunk during the Runewar.

Chantilly. A rugged and mountainous island famous for its prosperous mines and dangerous wildlife.

Demarchy of Bronze. Home to the forgewrought, who live here in mechanical cities that crawl across a plain of sentient grass.

Drakfell. Dragons live on these vast steppes. When the local mammoths grow sparse, they go hunting further abroad.

Eard. This prosperous island was settled by Iontan clans many centuries ago and is now split into Five Kingdoms, which are sometimes aligned and sometimes in conflict.

The Feystones. The veil between the worlds is thin on these islands, and the forces of chaos hold sway. They are home to the wild fey, who don’t acknowledge the King of the Summer Court.

Isle of Dawn. This unusual island is difficult to find. Strange priests worship the sun here and are said to know profound secrets.

The Jotanay. This is the home of the giants, and is a land of towering peaks, boundless skies, and vast, treasure-filled ruins.

Kryry. This jungle-covered island is home to terrifying monstrosities. Legend says the lost city of Aurelia, where magic reached its antediluvian peak, lies here.

Lipany. A land of gloomy swamps and ruined towers. The hills in the north are blessed with an abundance of gemstones.

Midnight. This region of unending darkness was home to the Kith before a remarkable catastrophe saw many of them perish and the rest flee. It is said there is a city here that sits on the threshold of the land of the dead.

Myrr. This island was originally settled by Fyalan clans fleeing the Aarunian invasion of eastern Senica, some of whom befriended dragons and were called Drakewardens. These rolling plains are now only sparsely populated.

Rajeca. Magic behaves unpredictably on this wild island which is crisscrossed by flowing rivers of vegetation and inhabited by sinister spider-folk.

Sardath. Minotaurs called this island Kalégay and created a sophisticated society here. But some offence against the Fey saw abominations rise from the sea and destroy everything.

Senica. The largest island and home to the original four human tribes: the Ionta, Andella, Vendia, and Fyala. Numerous city-states exist on the coast, including Iskandar, the largest city in the world. There are other remarkable features here, including the Abyss, where once stood the capital of the Vendian Empire, the Wyrdwood, which is the home of the Summer Court, the wild Andellan Valley, and the steppes of the God-King to the north-west.

Skalica. The merchant princes of Skalica sail the known world seeking trade goods. The island also harbors many pirates, and the difference between prince and pirate is not always clear. In recent years, Skalica has come under the influence of a grim figure called the Pale Lady, who dominates the decadent city of Zalim.

Sornlands. Here, the Queen of Ice and Snow reigns over her human and vargr subjects, dreaming of Greatwinter’s return.

Wandering Isles. These slow-drifting islands are home to enormous sentient mountains that occasionally offer advice. The famed raft-cities of the jotunkin often float here.

Yenn. High above this volcanic archipelago, the Skyriders of Yenn live in their floating hamlets and navigate the air in their glidecraft.

Zibah. In ancient times, a group of exiled kith left Midnight and settled here. Most lead a nomadic life on the verdant plains in the south, which are inhabited by bizarre and deadly megafauna.

Iskandar’s influence extends over an enormous part of the surrounding countryside, which is referred to in the city as “the province.” This area is bordered to the south and east by the Andalan Mountains, to the west by the Sea of Orbs, and stretches nearly thirty miles north to the Cerulean River. Over a hundred thousand people (not including the population of the city, which is sixty thousand) make their home in this region, dwelling in over three hundred settlements that range in size from hamlets of a few dozen souls up to major towns of several thousand.

Settlement names vary greatly and reflect the different cultures that have influenced the region over the years. Some examples include Abary, Deepwater, Froun, Jezail, Moonmire, and Zahomy. Some parts of the province have settlements clustered closely together, while other parts are very sparsely settled. These later regions are often home to monsters, fiends, and brigands, and the settlements there can feel very isolated indeed.
