Lonely Light is one of the Iron Islands. It is a minor outlying island, not one of the main seven in the chain. The Iron Islands are actually formed in two clusters. The main group has about 30 islands in it, including seven major ones. There is also a small secondary cluster, however, a few days' sail to the west: it is composed of a dozen rocky outcroppings and atolls, of which Lonely Light is the only inhabited one.
