The Isle of Deeds lies in the southern seas of Britannia, east of the Cape of Heroes. It is a quiet island, covered with grassy plains and small forests. Located on the island is Serpent's Hold, the fortress of Courage. During the Ultima VII era, the Fellowship's Meditation Retreat lies on a small island a little to the east.
The island hadn't changed much over time, although has became more built-up, with several new buildings erected around the fortress of Serpent's Hold.
