Hollow World Set Hollow World Arctic Cap
The pair of Hollow World Set Outer World Arctic Cap, this map showed the northern polar gate from inside the Hollow World. (See the Outer World map for an overview of this set of maps.)
The Hollow World maps suffered from few of the stretching problems that plagued the Outer World, as they mainly presented the wholly new internal world. That said, the parts of the Outer World shown here were indeed stretched. This map also made clear that the darkened Sunless Area was shared by both maps, with the same bits of land depicted inside it. It’s not quite clear which parts of these maps were intended to be part of the lip of the polar openings, but at the least this darkened area must surely be included as part of it.
