Cradles once floated down the River of Cradles. Their records appear in Godtime archives, and sporadically in the First and Second Ages. Jrusteli God-learners plundered the cradles for the many magical artifacts meant to keep the giant children safe and help them grow into powerful giants. Zola Fel is the river god of the River of Cradles.
At first the Jrusteli boarded the cradles at sea, but too many evaded them and reached their destination. The greedy Jrusteli built the city of Corflu on the mouth of the river, only to find that the nomads of Unknown were robbing cradles before they reached that point. Finally, about 750, the Jrusteli founded the city of Robcradle further up the valley to catch the cradles before the nomads got them.
Robcradle was destroyed by the giants, and the river itself doomed Corflu. By the start of the Third Age, the valley was calm and serene, but barren of cradles.
Since the beginning of the Third Age, the river valley has provided an excellent grazing ground for the warring tribes of Prax to fight over. Now that the Unknown has arrived, the valley is being pacified for Lunar farmers to settle and work the fertile river valley.
