Life cycle
The Krafayis are a race of intelligent and brutal beings. During their early life they are nurtured in a similar way as a bird would be. After about the age of several hundred they go on a never ending voyage with up to three thousand other Krafayis journeying across the universe and devouring creatures they find.
