The lake at the edge of a desert was an oasis for many for within that lake lay an abundance of life, of various fish and sea creatures that provided sustenance for the Tribe. However, there were times when the lake was barren, its produce scarce especially during the times when the weather was bitter and cold. One year, the fishermen and their families were starving. The food they had imported had been running out and many had died, including the young. It seemed the fishermen of the Tribe would be no more. The leader of the village prayed to the Gods, crying and on his knees. Praying that his people would be saved.
The next morning, when they went to sail they saw the corpses of fish casting a black shadow across the lake. Upon further inspection they saw that the corpses were sizzled, as if they had just been cooked for consumption. The villagers didn't care however. The Gods had answered their prayer.
They were, however a meagre few who wondered how something so logically impossible could occur so they built a tower to observe the lake. They observed day and night, when the moon cast its silver light across the lake and when the morning sun made the lake look a mirror reflecting the glory of the morning. A breakthrough came at the late hours of the night when one of the observers noticed an orange glow permeating the dark depths of the lake and a wailing sound that echoed in the night.
That wasn't the last of the sightings.
One fisherman who was out sailing in the dark and he saw a tail made of stone ascend from within the lake. Below him, an orange glow blazed to life and as quickly as it had appeared, the glow disappeared.
The mystery was never pursued any further for during times of struggle, the head of the village would pray and the remains of fish would float on the empty lake. The Shaman knew this was the work of a Guardian.
And so, day after day the people found the bodies of fish until the day Emon came to carry out the sealing.
That day, Emon saw the corpses of his men floating on the lake. He stared down to see the sword washing up at shore, the colossus wailing in the distance.
