Two generations ago, a magnificent couatl saved the woodland village of Pearlglen from a devastating plague. The villagers built a statue in its honor and enjoyed decades of peace. Now, the “savior” has returned, demanding heavy tolls and draining the town’s coffers to build a magical ward. Shrine of the Feathered Serpent is a D&D 3.5 adventure for 12th-level characters by Skip Williams that trades the usual world-ending threats for a highly lethal, magically-backed extortion racket.
Introduction: The Extortion of Pearlglen
Originally published as a free web enhancement, this adventure drops players into a town gripped by economic panic and hidden tyranny. The prices in Pearlglen have doubled, the roads are blocked by toll-collecting wardens, and the local priests are acting incredibly strange.
The brilliance of this module is the grounded nature of the villain’s plot. The town hasn’t been conquered by an invading army; it has been hijacked by two cunning opportunists exploiting the villagers’ historical reverence.
Narrative Core: The Con Artists
The masterminds behind Pearlglen’s misery are an unlikely duo. Lerrius is a neutral evil Forest Gnome Ranger who makes his living poaching unicorns and other fey creatures for black-market parts. He recently teamed up with Hobliah, a highly intelligent Spirit Naga Sorcerer.
Knowing the legend of Tlanextic the couatl, Hobliah uses Disguise Self to appear as the village’s feathered savior—conveniently lacking wings due to the spell’s limitations. Together, they have murdered the village’s true leaders, magically Dominated the remaining acolytes and guards, and set up a false temple in the nearby ruins to collect the town’s wealth.
Tactical Breakdown: From Forest to Shrine
The adventure scales nicely from an investigative town sequence into a brutal wilderness trek, culminating in a multi-monster boss fight.
1. The Wilderness Ambush (Area A5)
Lerrius doesn’t wait for the party to reach the temple. If the PCs ask too many questions in town, he sets up an ambush on the forest trail.
- The Tactics: Two Dire Bears (CR 7) block the path and engage in heavy melee. Meanwhile, Lerrius hides on a platform 30 feet up in the trees. Using his Hide +30 (in wooded areas) and the Manyshot and Rapid Shot feats, he peppers the party with arrows while the bears tear into the frontline.
2. The Temple Entrance (Area B1)
The ruined temple’s entrance creates a unique moral dilemma.
- The Guards: The doors are guarded by two human Village Wardens. They are entirely innocent, acting under Hobliah’s Dominate Person spell. If the 12th-level PCs simply unleash their most devastating area-of-effect spells to breach the door, they will be murdering the very townsfolk they are meant to save.
3. The Worship Chamber (Area B2)
Hobliah holds court in a massive, open-roofed chamber filled with piles of floral tributes.
- The Illusions: She rests atop a three-tiered ziggurat, maintaining her couatl disguise.
- The Back-Up: If combat breaks out, the fight quickly escalates. Hobliah is supported by eight Gargoyles hiding among the ruins and a massive Behir that slithers in from an adjacent chamber to swallow PCs whole.
The Boss: Hobliah (CR 12)
Hobliah is a Spirit Naga Sorcerer 3, giving her the spellcasting capabilities of a 10th-level Sorcerer alongside her innate Naga abilities.
- The Tactics: She uses her Charming Gaze to pacify aggressive fighters, directing them to look at the “treasure” in the next room while she deals with the spellcasters.
- The Spells: She relies heavily on Evard’s Black Tentacles to lock down the battlefield, follows up with Unholy Blight, and casts Haste on the Behir and the Gargoyles to overwhelm the party with action economy.
System Conversion: 3.5 to 5e and OSR
Updating this con-artist duo to modern systems is highly rewarding.
For 5th Edition (5e):
- Hobliah: Use the Spirit Naga stat block, but give her access to 4th and 5th-level Sorcerer spells (Evard’s Black Tentacles and Dominate Person are essential).
- Lerrius: The Archer NPC stat block (from Volo’s Guide to Monsters) combined with the Gnome’s racial traits works perfectly. Give him a Cloak of Elvenkind to represent his absurdly high Hide checks.
- The Behir: The 5e Behir (CR 11) is a terrifying monster that will perfectly complement the Naga’s spellcasting.
For OSR Systems:
- The Dominate effect is the crux of the town’s mystery. Ensure players have access to Dispel Magic or Protection from Evil, otherwise, the innocent villagers will be forced to fight to the death.
GM Tips: Unmasking the Serpent
- Play the Cult: The dominated acolyte, Hetagg, truly believes Tlanextic has returned to save them from a new plague. He will happily defend the extortion, telling the PCs that the “civic project” is for the greater good.
- The Wingless Clue: Emphasize Hobliah’s appearance when the PCs finally meet her. Describe her radiant, rainbow-colored feathers, but let a high Perception/Spot check reveal the complete lack of wings—a fatal flaw in her Disguise Self spell.
- The Real Couatl: As suggested in the module’s “Further Adventures,” having the actual Tlanextic show up after the PCs kill Hobliah creates a fantastic roleplaying moment, especially if the town is still skeptical of the party’s actions.
Conclusion: A Masterful Bait-and-Switch
Shrine of the Feathered Serpent takes high-level characters out of the planar-hopping, world-saving mindset and grounds them in a gritty, localized mystery. It requires players to use non-lethal tactics against mind-controlled innocents, track a poacher through the woods, and dismantle a highly coordinated monster syndicate. It is a fantastic palate cleanser for a high-tier campaign.
