From publisher blurb:
Blood Tide is the first adventure in the Shadows in the Mist campaign. It can be played as part of that campaign or as a standalone adventure.
The city of Anvilgard is under threat: Ghoul-infested ships prowl the Searing Sea and attack any vessels that leave port; the aggressive growth of the surrounding jungle threatens to choke the city, and pustulent abominations of Nurgle have washed up in the harbour. Now a Kharadron airship carrying vital supplies has gone missing, thought to have crashed and drowned below the waves. The sun rises red on the City of Scales, bearing the ill omen of the Blood Tide…
Blood Tide takes a party of Soulbound heroes to the mist-shrouded streets of Anvilgard — and to the tumultuous seas beyond. Joining forces with the Aelven corsair Theriel Kaltis, the party sets sail across the Searing Sea in search of a downed Kharadron airship, along with its precious cargo. To reach the downed vessel they must contend with the beasts that dwell below the waves — and the horrors that sail upon then.
