The inland village of Waknuk (Wabush) is in southwestern Labrador. Labrador has become a much warmer place in the fictional future, with large tracts of arable land. Rigo (Rigolet) is the capital of Labrador and the fictional government in the book, a fairly large river town near the east coast. The port of Lark (Lark Harbour) is mentioned as a way-point on the west coast of the island of Newf (Newfoundland) where sailors may obtain provisions.
A large island to the north-east (Greenland) is rumoured to be inhabited by an amazonian people with bizarre habits. Northern islands are described as being cold and inhabited chiefly by birds and sea animals (islands of Nunavut). Uncle Axel, a former sailor, has travelled far to the south of Labrador, and from a distance seen the "Black Coasts", where there are areas with what look like ruins of the old civilisation. He also recounts second-hand tales of South American primates living in forests.
Later, the existence of geographic areas far less affected by the nuclear exchange and fallout are established, particularly Sealand (New Zealand), which is home to a socially and technologically advanced society where telepathy not only is the norm, but is encouraged and developed as a survival advantage.
