Tall tales of hidden riches are common in the pirate-infested taverns of the Shackles, but when Captain Varossa Lanteri claims to know the location of the secret treasure hoard of legendary Captain Jemma Redclaw, it seems she may be telling the truth. Captain Lanteri hires the PCs on as crew to help her assemble the magic key that will open the door to Redclaw’s treasure... and the ancient cyclops stronghold in which it’s hidden! Can the PCs survive long enough to claim their share of the lost loot, or will their enemies—or their allies—send them to a watery grave?

Fangwood Keep has changed hands innumerable times since its founding decades ago on the border between the warring nations of Molthune and Nirmathas. Over the years, both countries have sacrificed money and soldiers in an effort to control the fortress along the Marideth River valley, both for its tactical location and for its secure defenses. Recently, however, the battles around Fangwood Keep have dwindled to a trickle as Nirmathas has firmly rooted itself in the surrounding valley, allowing the tide of war to shift elsewhere and peace to settle at last over Fangwood Keep. This respite was shattered by the arrival of a renegade Molthuni commander named Pavo Vos. Obsessed with capturing Fangwood Keep and unraveling the fortress’s mysteries, the defecting lieutenant unlawfully used his platoon to secure the castle, much to the ire of both the Molthuni and Nirmathi governments. Now the task of bringing Vos to justice and reclaiming Fangwood Keep for Nirmathas lies solely in the PCs’ able hands.
