And now, the TOTALLY DIFFERENT SUPER UPDATED VERSION:
The ancient towns Kadaikos were built on and around the Great Lake, with large columns anchoring the towns on the lake.
The Lemurs, under the guide of Laanx, invented great devices and techniques. The lake towns specialised in fishing while the lakeside towns specialised in farming the rich soil. Each town had a leader chosen by Laanx himself, and these formed the Council of Kadaikos. Thus the towns prospered and grew, and each town held at least a thousand souls.
But like all great nations, it would not last forever. One day Laanx stopped appearing to the Council. Inside the sacred meeting vault located in the middle of the largest town, a black flame appeared on the brazier which usually held the image of Laanx. The Council met and discussed this, and concluded that the black flame must be some form of Laanx.
But the black flame was cunning. Slowly it started taking control over the Council?s minds, until all ten towns were ultimately serving the flame. The Council became ugly and spiteful things, refusing to come out of the Sacred Meeting Hall, except to give orders to a waiting servant.
The Council then proclaimed a law which stated that anything given to the Lemurs by Laanx was contaminated and should be destroyed. The people complied, thinking it the wish of Laanx himself. Eventually all light-giving things were destroyed and the Lemur society was reduced to a mere fraction of its former glory.
In the darkness, the black flame could spread its taint, and the former towns of Kadaikos fell into chaos, and the minds of the people ravaged. The Lemurs became evil and spiteful, fighting among themselves for basic things like food and territory.
But in the darkness, in one of the former mines, a group of Lemurs had managed to save and repair some of the light-giving things. Slowly they multiplied, until there were eventually hundreds of them living in the lighted tunnels under the ruins of Kadaikos.
But the black flame was strong and could sense the presence of light weakening it, if only slightly. The black flame sent its minions down into the tunnels and the true Lemurs were forced to flee into the network of tunnels and caves known as the Stone Labyrinths. These lived many years in the labyrinths, and forgot much of their history. Then they came across long-forgotten Yliakum and settled there.
