This lake has a large number of various people who live on its shores. If you are an Elf, you likely come from this region. The Ekujae live to the west, the Kallijae to the north, and Alijae to the east. This area is a hodgepodge of various cultures and peoples. Merchants, scholars, explorers, etc.
If you are a geomancer, consider coming from this area as they study the leylines of magic that surround this lake.
Nemshenzu
This is the largest Lizardfolk stronghold in the Mwangi Expanse. Located on the eastern shore, the design of the city is such that only aquatic animals can travel around without drowning.
Spire of Destiny
Large towering formation of pure white rock of seemingly supernatural creation in the very center of the lake. While many come to study it, they can only do so from afar as the local sealife is unusually territorial and powerful. Rumor holds that those who can make it to the center of the lake can ask a question of The Guardian of the Lake and it will answer in a parable or a riddle before going back to sleep. The increased number of people building cities along the lake has driven more and more wildlife to move towards the center, increasing the lethality of attempting to reach the spire.
