Pontus

Pontus is a large city/region located inside the vast crater of Pontus in eastern Westros. The city itself lies near the middle of the crater of Pontus which was created during the Downfall of Numeron as this was the exact spot that one of the three Magi centers was that directed how the spell was cast, and its destructive effects created the massive crater that sits there now.

The city isn't even close to large enough to cover the whole crater, and througout the vast exapanses of the crater the existence of farms which in case of a siege produce enough food to sustain the city's population. The rim of the rises so high that only through the opening for the Talabec river, and through one sharp drop in the north are their even ways into the crater. Their are three Pontus made entry points located in the rim of the crater and these tunnels are guarded by two fortresses, one at each end. Due all these formidable defensive characteristics the city is considered all but impregnable

Geography
The river Talabec flows around the edge of the crater, bringing with it the possibility of trade links to the rest of Europe and through this has allowed the city vast riches. A deep harbour with an associated settlement called Talagaad is located near the western rim of the crater – from here a tunnel passes though the crater wall, each end protected by a fortress. This tunnel is the only way into Pontus, and it is no surprise that the city is virtually impossible to capture.
