Discovering the Forbidden: Some secrets should remain hidden?

Quasi-realistic, Pulp-style Action, with a bit of Monster Hunters flavoring. "Mystery-Thriller," not "Investigation."

Since the end of the War of the Quadruple Alliance in 1720, relations between Britain and Spain remain strained to the point of near-conflict, and will, once again, tip over into "limited" warfare in 1727. Or, at least, this would appear to be the Central Tension in the region, to the unaware…

• Expect to encounter wildly-improbable underground "puzzle" architecture.
• Expect to encounter "real" supernatural creatures and events, both friendly and hostile.
• Expect to occasionally face opponents you can't possibly defeat in combat, and must outrun or outwit.
• Expect that you might have to surrender and be captured, due to the previous point.
• Expect to occasionally have to operate outside your existing skills and gear.
• Expect campaign rewards to come with strings attached.
• Expect some naval combat (though probably not until you have a better ship).
• Expect your ship to potentially be commandeered/pressed at some point by His Majesty's Navy.
• Expect to upgrade the ship at least once.
• Expect to be caught up in wars and rumors of wars.
