The Sea of Shadows was a region no sane man dared to venture. The seas of Rokugan were hazardous at the best of times; when combined with the foul touch of the Shadowlands they became an area of unimaginable danger. A man who fell overboard in a storm was almost certainly dead, or may as well be. The storms that blew over the black waves possessed a malevolent hunger. Creatures beyond description skulked beneath the water, constantly seeking living prey to torment and consume. Even the Mantis Clan, who claimed greater mastery of the sea than any other clan, did not challenge the Seas of Shadow.[citation needed]
