Newhaven Basin is a geographical region of Kings surrounding the mouth of the river Abby. The basin is an extension of the valley of the Abby and is itself extended by the Newhaven Bay. The basin is the most urbanized part of the isle's landscape but most of the nature has remained intact. Besides the agglomeration of Newhaven and some farming grounds southwest of the city, the basin is covered with pine forest. The richness of this region comes forth from the minerals carried from the southern mountains by the Abby.
