The Rod of Seven Parts
The Vast Swamp is an area of swampland that acts as a de-facto border and separates Cormyr to its west from Sembia to its east. It is flanked to the north by the Thunder Peaks mountains and to the south by the Dragonmere, a body of water. The terrain is dominated by undergrowth and bogs with precious little clear, dry land to be found anywhere within its borders. Cypress, black gum, water ash, water birch and willow trees choke the region, making it appear more like a flooded forest than an actual swamp while stunted oaks and blueleaf trees surround the swamp as well. Fog from the Dragonmere coast rolls inward towards the swamp constantly, whether in the depths of winter or the height of summer, forever shrouding the place with a murky fog. Even on the sunniest days the entire swamp is coated with a thin mist, making it difficult to see more than a mile in any direction (assuming you can find a vantage point high enough to stop the trees obscuring your vision). Other features of the swamp are the disease-carrying insects, noxious clouds of gases, patches of quicksand and the bone-chilling rain that falls thereabouts. The borders of the swamp are forever expanding towards the Way of the Manticore, albeit slowly but when it finally reaches that far it could halt all overland travel from Sembia to Cormyr. The Vast Swamp is the source of the Darkflow, a river which flows from the Vast Swamp south into the Lake of Dragons and forms part of the border between Cormyr to its west from Sembia.
The Vast Swamp is known to be inhabited by; Gnolls, Gobliniod types (Hobgoblins, etc), various Lizardfolk, Trolls, catoblepas, and will-o’-wisps, a rare few hydras, small black dragons and grells and there are rumours of mind flayers, beholders and liches amongst other things. This myriad of monsters make the Vast Swamp the most dangerous place in Cormyr and neither Cormyr nor Sembia have any particular interest in laying claim to the land. Thankfully, the monsters are content to war between themselves rather than raid the surrounding lands. The Vast Swamp is the most common place to find Meazels.
