The Kantas Expanse is a shared campaign setting for D&D 5E, in a similar vein to the West Marches. On Toril, the same world as Faerûn, with Baldur's Gate, Neverwinter and all those famous adventurers, this is set on a distant continent fraught with planar portals, conflict and mystery. 

The action is centred around Daring Heights, a Faerûnian town settled on the site of a strange portal that linked the two continents, though the portal has since been partially destroyed. Primarily focused on mercantile endeavours like finding new trade partners among the civilisations of Kantas, Daring since its founding has also focused on bringing in a healthy population of adventurers. It's dangerous to go alone, after all, and merchants and diplomats don't always make the hardiest of travellers.

Most adventurers here come from Faerûn originally, either paying to teleport directly to the bustling town of Daring Heights or braving the several month long voyage across the sea to arrive in the rapidly expanding harbours of Port Ffirst. Though many choose to stay by the coast in Port Ffirst, and still others are drawn to the hub of Daring Heights, the adventurer's lodging of choice is Fort Ettin. Pulled from the earth by an Archmage and originally run by three brothers, this half-fortress, half-tavern specifically caters to the adventuring class. One of its main features is a large board known as the Rumour Mill where citizens pin notices of jobs they need doing or other adventurers pin places of interest they hadn't had the opportunity to explore themselves. 

Beyond the walls of these settlements, forest stretches out far to the north and south, to the extent that few have even seen the other side of them. A long mountain range marks the western edges of Daring's maps and the sea to the east has barely even been fully sailed around. Though many other groups have been met - the Kobold City of Kundar, the Bearfolk's lands, the minotaur/air genasi republic of K'ul Goran, the Erinas' village, Vorsthold - the edge of the map for most adventurers lies a scant few days walk in any direction. And the edge of the map is where excitement always lies... 

But it also holds monsters. Especially with the land's strange propensity for portals and tears into other planes, the range of creature and occurrence encountered have already been the stuff of legends, and the town is only 3 years old. Twisted half-shadow mutants known as the Twilight have sown chaos in the region, and an entire orcish horde descended once upon Daring's fledgling walls. The town has been lost, burned, reclaimed and rebuilt already within its short lifetime, and life doesn't look to be getting any quieter. 

Witches who can sell you anything for a price, elves who reincarnate through a mana pool, Kobold mansions which lead to ancient dwarven schools of illusion, tears in the fabric between the Material Plane and the Feywild that spill uncontrolled emotions into the world, all these are merely a handful of the strange tales being told around the fire at Fort Ettin. What tales will you tell?
