The left sketch is the humble home of a humble wood cutter who just happens to have a magic axe which can cut down trees in a single chop... but only if the tree is ready to die. She lives in the WaterVault.
The center image is the aqueduct which connects the WaterVault to the city of Sarifer, which south on the plain below the foothills of the Karzkas Mountains. It was built after an earthshake caused the formerly reliable River Wendolyn to dry up every summer. It enters the city at the WaterGate (north)
The right picture is the SeaGate (east)of Sarifer. It is the main gate leading to the major trading port city Adaron. All the best houses have been built for centuries along the inner wall facing the road coming up the gently sloping plain road, where the rich could watch the wagons bringing them even more riches.
