The City itself sits at the southwest side of the artificial mountain of Erythia. The lands to the northwest of the City are generally referred to at the Dark Valley. Here, there can be found a mix of integrated races where most thinking and civilized people have gathered together to form towns against the faywilds and the shadowroads, most of which have been lost to history and are open now to only fel-things. Were open war to come to Gavin Wel from the Blighted kingdom of Beris, it would be imperative to open these roads again and unite the peoples of the Valley into a defensible military of somekind. 
The mountain of Gavin Wel, Erythia, where the present metropolis surrounds is actually a massive ancient forge built by Raelfaen with the help of the titans, the tiefling and the ShadarKai late in the fourth age of the world nearly fifteen hundred years ago. Originally a smelting plant for the first Cathoid alloy, mined from veins in the earth and turned into weapons, armor and coin currency, local lore is replete with ancient songs of heroes who helped with creation of the forge. Now, Erythia, long drained of its cathoid, a substance now believed to have some connection to the Blight that threatens the Valley at Gavin Wel, stands as a constructed volcano with eternally rivers of molten lava running down steep canals.
