Tallest peak and lowest valley?

Could be both were tarns, turned lakes, but silted up after the ice retreated. The earthworks of creating a large city caused a compacting or other interruption of the silt in what was to become the LOIO, which then displaced groundwater, causing it to rise up from the spring that feed the water that ended up on top of the lake and flowing down into the sea by the port.

This is more likely than a "curse" causing a whole lake to appear and a city to sink. Also possible historical revisionism by later emperors (Rile wasn't too fond of daddy Venril) to explain why they wouldn't rebuild Veksar considering there was ample time to do so between the rise and fall of the Sathirian Empire.

Say what you will about the Iksar, but even when sunken into a lake and driven from their capitol, most of their buildings remained. Civil engineering is apparently one of their strong suits. Looking at you aqueducts of Sebilis.
