The Sharku'u are almost unknown, living deep within the ocean, but venturing to Val'ri Bay every year to spawn. No Sharku'u yet known has died of natural causes, since most are killed in battle or in the hunt by age 30. The longest-living Sharku'u managed to survive until age 70, and was known as the Ravener. They have almost an obsession with being 'fit' (Darwin, eat yer heart out!) and are ritual cannibals.
