Hollow World Set Hollow World Planetary Map v2
For the full story behind this map, see Hollow World Set Hollow World Planetary Map.
As with the Hollow World Set Outer World Planetary Map, there was an art error in this map, with Lake Chitlaloc appearing as plains instead of water. A second error lay in the shading of the nearby Malpheggi Swamps, which were coloured light brown surrounded by a river.
In keeping with my corrected version of the Outer World map, I have fixed these two problems, leaving everything else as is. Lake Chitlaloc was an easy fix, but the Malpheggi Swamps posed more of a problem, since no other swamps were marked. I have therefore adapted the hex map swamp colour, changing the whole area ringed within the river.
