Maharta is built on a river delta into the sea. It's suburbs stretch onto many different islands.
The military of Maharta is said to consist of war elephants.
During the Serpentwar, the Emerald Queen's army seiged Maharta to use it's ships to enter the Kingdom. Realising this, Calis and his gang burned the shipbuilding facilities. This stopped the Emerald Queen's advance for many years.
