Players in my most recent game kept hearing stories about sea-side villages getting attacked by some kind of water beast. Eventually when the players defeated one of the big bad guys (an powerful wraith named 'The Black Demon'), the bad guy gloated about spreading the plague to an underwater leviathon he called Khethouth. This plague made all creatures it infected with a super aggressive zombie-like infection.
The players previously discovered that this plague only effected intelligent creatures so they came up with the brilliant idea of using spells to make the target less intelligent (feeblemind) as a way of weakening the plague enough to remove it with a few remove disease spells. The players created spears and arrows that were enchanted with the feeblemind spell and set off to find the sea leviathon Khethouth.
The players modified an old fishing vessel to be armoured and armed with seige weapons and used spells to track down the beast. When the beast attacked it latched onto the armoured vessel with its central jaw whilst its other heads attacked those on the deck of the ship.
When the players finally defeated the Leviathan they found out that Khethouth was not actually a sea monster at all, but rather a Great Dragon from another realm. Khethouth was visiting the player's realm because he foresaw that an evil, Nortia Damius (a demigod), from this realm/plane will eventually find its way to Khethouth's home realm if not stopped. Khethouth then instructed the players that they need to destroy Nortia Damius. And taught them how to be prepared.
