Hunt the Most Dangerous Game in the Known Worlds! The jungle planet Leviathan teems with mammoth lacerauns, savage beasts of enormous size and cunning, potential trophies unmatched in any other star system. Intentionally undeveloped beyond a few tourist-oriented settlements, Leviathan nonetheless draws more than just adventure-seeking hunters, but researchers and those who would see the world left completely untouched. A setting sourcebook for The Last Parsec, Leviathan contains new locations and characters for the planetary system, new setting rules for Leviathans natural dangers, a Plot Point campaign, Savage Tales, and a host of new creatures.
