After the War of a Thousand Battles, the merfolk and aquatic elves thought they'd completely exterminated the sahuagin menace from their cavernous homes on the Western Shelf. But a few of the sahuagin survived, and bred, and hated the merfolk and the elves for their attempt to exterminate their race.
Now they've massed an army, and the roar of their underwater ballista rock the northern walls of the merfolk kingdom.
Now, get a ring from the king of the merfolk while all this is going on!
War in the Deep is a 4-encounter D&D 4th Edition heroic tier adventure that's been designed so it can be scaled for 1th through 9th level adventurers. The climax can fit into part of a larger quest or campaign, or the story can be left as a one-shot adventure. It's designed to be highly flexible, easy to run, and exciting for players and DM alike.
Each monster is presented in three variations, one for 1st level adventurers, one for 5th level, and one for 9th level. As a result, it's easy to tweak the monsters for any party from 1st to 9th level.
In addition, each piece of dialogue is presented in two columns: a carefully-written piece of dialogue that you can read as “boxed text,” and a detailed summary that you can customize according to your preferred speech patterns.
The PDF includes both portrait (for easy printing) and landscape (for easy reading on a laptop) sections. The full-color artwork and maps have been carefully color-corrected to print perfectly on color and black-and-white printers.
You can get this adventure at DriveThruRPG for a mere US $5.
