I designed and drew a full-scale (1.03×1.45m) ordnance map of a fictional island for Vexacus’ online serial.
Zordnia Island is a mysterious island-that-shouldn’t-be-there in the Pacific, known but obsessively avoided by the Polynesians of the nearby islands. Basically they had a bad run-in with the prehistoric alien robots (yes, you read that right) deposited there a while ago, left, and never came back. Currently owned by the US military and has security that makes North Korea, Fort Knox and Area 51 look like the neighborhood watch.
The vertical text is deliberate as the map is supposedly made from the perspective of a surviving Japanese Empire.
