The Kalanguya people believed that the surface of the earth was
flat, replete with abundant resources to meet all their basic needs.
But one summer time, the god of the Kalanguya people did not allow the sun to shine for more than a month.
Then it had begun to shine only at about 10:00 to 11:00 o'clock in
the morning. The people termed the tragedy "Natalok
I Eggew".
In the darkness, the people groped for their way while doing their
daily chores. Because everything they touch would
wriggle or move, they thought that they either held a wood or snake.
Immorality happened during the tragedy and many women got pregnant. These caused the massive death of women due to childbirth or tapi.
