the known world
The towers of Sharn reach up to the sky, but its tunnels also streich down into the earth. Beneath the decrepit and forgotten ruins of the Depths. these undercity warrens are known as the Cogs.
The Cogs sit at the vcery base of Sharn and serve as the center o fits industry. Well-maintained tunnels and shafts grant access to this deepest part of the city, allowing workers to make their way between the Cogs and the surface on a daily basis. The Cogs are the churning heart ofthe city. full of forges and foundries powered by steaming geysers, molten rock, and bound fire elementals. Extending far below the foundations of Sharn’s towers, the Cogs incorporate elements of ancient ruins and natural caverns. Farther below lies an enormous lake of magma, the heat from which rises into the bowels ofthe city. Most people, residents and visitors alike, never venture past the furnaces of the Cogs to seek the fiery lake itself.
Few individuals live in the Cogs as a matter of choice. Those who work in the foundries have homes in Lower Dura or Lower Tavick’s Landing. and Khyber’s Gate is the only place in the Cogs where actual homes can be found. In spite of this, the Cogs do support a population of a few thousand. Criminals and fugitives hide from the law here, and forbidden cults and other sinister organizations set up temporary residence in the Cogs to practice their dark rituals.
