Talugrenna is the commercial centre of the Voivodeship of Transbileria. Very nearly all goods that can be bought and sold in the Voivodeship congregate in Talugrenna.
The city is fortified with high walls and the unique arrangement of the rivers around it. The initial settlement was established where the Talu River is met by its tributary, the Grenna River. Given the need for defence against the many vampires known to roam the Bilerian Mountains, early settlers put together a novel plan: to dig a canal upriver from the settlement between the Talu and Grenna rivers. Since vampires cannot cross running water, the city is considered a safe haven from those undead beasts.
