The Riviga Kiziph Delve
This delve was probably founded sometime around 300, but the exact date is unknown. It sits on the northern edge of the mountain range south of Caldonacia, and is south of The Gora Delve with whom they have close ties. The Riviga Kiziph Delve has worked closely with the Gora Delve for over a thousand years, and was instrumental in turning away an attack by orcs and ogres in the 400's, and helped again in the 600's when Gora accidentally opened a route to The Underdark, which needed to be defended and sealed.
