Concept sketch of the Water Temple in Mortal Kombat: Deadly Alliance
The Water Temple is an ancient location found somewhere in Earthrealm. This arena was only in a concept sketch within the Krypt and Extras kontent gallery of Mortal Kombat: Deadly Alliance and never made it into the game's production.
This temple was used only for the worship of water, the very life-giving element that has been revered as the source of all creation.
It is unclear whether this arena has something to do with the God of Water who appeared in Mortal Kombat Mythologies: Sub-Zero. Its location is also unknown.
