Sewers of the Underguild is an adventure designed for characters of at least 11th level, and characters up to 15th level will find plenty of challenges. Hidden within these narrow passages and filth-filled channels is a guild of vampiric rogues, led by their master Sangre and his aide, a nycaloth called Ankoz. Deadly traps abound, so a skillful rogue will be a lifesaver. Because of the high likelihood of desperate combat with numerous vampiric and monstrous opponents, it is suggested that a cleric and at least two fighters be prepared to beat back the many watchdog monsters the guild employs. You can hide the locales in Sewers of the Underguild in any ruin or location that fits your campaign purposes. A thriving metropolis that just happens to have a large crime and vampire problem would fit the bill nicely. In the Lost Lands campaign setting of Frog God Games, the Underguild is located in the sewers beneath the ruins of Curgantium, the ancient imperial capital of lost Hyperboria. Located at the edge of the modern Kingdom of Foere, the Underguild still finds itself located centrally enough to pull the strings of its weblike network running throughout the former lands of the Hyperborian Empire.

The Pyramid of Amra is a challenging adventure designed for characters of at least 12th level. Due to the nature and numbers of undead enemies (vampires), having a cleric on hand with the ability to cast raise dead and greater restoration is advisable.

In this adventure, the PCs travel to the Pyramid of Amra and the ancient Monastery of Night, where they face one of the most dangerous of opponents they are likely to meet, C’nosretep the Champion of Set.

Panic grips Absalom when a huge crystalline sailing vessel appears suddenly in the harbor. Identified as the King Xeros of Old Azlant, the ship presents a great opportunity for the Pathfinder Society. You and your fellow adventurers are summoned by Venture-Captain Adril Hestram and dropped aboard the King Xeros to explore it and report back. Only, what you find isn't an empty vessel, but a sinister ship with a vile intent. Difficult and unforgiving scenario, typical of Greg A. Vaughan. Contains lots of monsters from the Ethereal Plane and a mysterious setting. If playing under Pathfinder Society rules, a six-player party is recommended, rather than the standard four for early PFS seasons. Using Pathfinder RPG versions of monsters reduces the lethality, as the constructs are no longer immune to critical hits and sneak attack damage, and the Xill no longer automatically bite for paralysis on a maintained grapple.

The giants are only a half-mile away - straight up. Giants and humanoids that sail down from the heavens? Where could they be coming from?

This module is not a simple hack·and slay expedition. It also involves diplomacy and wit; if the PCs attack everything in sight, they may be destroyed. But the adventure is not entirely negotiation, for it has a good share of hearty dungeon exploration as well. Pgs. 4-23
