Svth was a scout zokujin who lived in the Tamori Tunnels, deep within the Dragon mountains. When the Dark Oracle of Fire Tamori made the tunnels his home, the zokujin were forced to leave their burrows. In one mission Svth ventured too far into the Dark Oracle's domain, and found itself trapped in a small burrow by a Jimen no Oni. The zokujin was so anguished that it had been driven insane and would attack anyone who attempt to communicate with it.
