Way of the Wicked

Way of the Wicked is a six part adventure module, with a seventh book dedicated to adding content to the prior 6 books intended for use with Pathfinder. Created by Gary McBride and Michael Clarke (with contributions by Jason Bulmahn to the 5th and 7th books) of Fire Mountain Games and released 2011-2014, Way of the Wicked differs from every other published adventurer for a Dungeons & Dragons derivative in existence at the time of its publication (at least as far as the authors could find), by not only supporting evil characters (which many modules have done, to varying degrees of effort) but was made for them primarily and exclusively.

Talingarde is a large island (The books use England as an approximate size) where society flourishes under the wise noble House of Darius who a guided by the selfless church of the sun god Mithra. Corruption is exceedingly rare, the church ensures disease is contained, the people are united by their faith and bans on the faiths of the evil gods has rendered their worship virtually non-existant. That just can't do and one of the few remaining worshipers seeks its destruction. Cardinal Adrastus Thorn, High Priest of Asmodeus in Talingarde has spent decades gathering supplies and forces to one day take over Talingarde and instill a puppet on its throne. However mighty Thorn is, he can't hope to survive if the entire might of Talingarde is unleashed upon him and so he operates from the shadows, recruiting agents to act in his place.

One day a group of hardened criminals is sent to Branderscar prison, well known as the most secure prison in the realm, and branded to await their execution (or be made to labor in the salt mines till they drop dead from the work). Thankfully for these prisoners, Branderscar was never particularly active and has gotten by on reputation alone for a long time. Lately the security is lax. With the lack of real threats the warden has not been particularly active in the day to day management of the prison. In his place the corrupt Sergeant Tomas Blackerly has quietly toned down the number of guards and skimped on maintenance to embezzle the prison's funds for his own use, and complacent guards are often drunk on duty. Seeing this Thorn sees ample opportunity to gain four new recruits and arranges for an agent to pass them a magic veil containing all the items they need to escape and form Thorn's "Ninth Knot" of agents.

Tropes used in Way of the Wicked include:

Deal With the Devil: As an evil campaign there are a few opportunities to make such a deal.
Ensemble Darkhorse: Grumblejack, a fiendish ogre and the only other prisoner when the player characters arrive at Branderscar, was intended as a Crutch Character of an ally for the initial jailbreak. The character quickly proved popular with players and was given expanded roles in each future book.
Evil Versus Evil: Described as one problem even the most successful evil campaigns fall into and as such the book takes care to primarily pit the PCs against good aligned enemies. That is not however to say that there are no fights against evil aligned foes within the adventure.
Mary Suetopia: Talingarde is this to emphasis the PCs evilness for destroying it.
No Campaign for the Wicked: Averting this is the primary reason this adventure even exists.
Villain Protagonist: The entire point.
