Lake Anasta is a body of water located somewhere in North Africa. At one point, it wasn't a lake; just dry land, as located on its seabed is a temple.
In Desperate Intruder, Brains and Tin-Tin Kyrano mount an expedition in the hope of finding treasure in the sunken temple; they are aided by the archaeologist Professor Blakely.
