Silvan Basin

The Silvan Basin is a vast polar depression on planet Verthandi, created by an asteroid impact many thousands of years before human colonization.[1] The Silvan Basin is thousands of kilometers across and is large enough to encompass the Azure Sea, the Fox Island plantation, and enormous tracts of blue-green jungle.[2] The Basin Rim cliffs that form the perimeter of the Basin are the eroded remains of the ancient crater's edge. There are numerous logging trails and roads throughout the area.[3]
