News from outpost is worrying. The Leviathans, these terrifying sea monsters, converge towards the boarder and threaten the Kingdom. Will the Allies and the conscripts, mandated by each of the Guilds, contain them? Exploting is now dangerous: fighting is not easy and fleeing can be even more dangerous. But the opportunity is unique to prove your worth and use this influence to gain access to the throne.
in Abyss Leviathan, the Threat Track is replaced by the Border board on which Leviathan cards will be placed. When you Explore the Depths, if the revealed card is a Monster you can fight a Leviathan on the Border. Some new Lords and some Allies will help you fight, using their power. The player who killed the greatest number of sea monsters takes the statue and wins 5 extra points at the end of the game. But be carefull if you do not fight, you may get injured.
