Storming the Diamond Gate (2012)

Publisher's blurb:

A Pathfinder Society Scenario designed for levels 3–7.

Agents of the Pathfinder Society have discovered the location of a back door into their private demiplane that puts the entire realm at risk of plunder and exploitation at the hands of the Aspis Consortium. Rather than close the access point into their adventuring paradise, however, the Decemvirate sends a crack team of Pathfinders to secure the gate for future Society use... at any cost.

This scenario is designed for play in Pathfinder Society Organized Play, but can easily be adapted for use with any world. This scenario is compliant with the Open Game License (OGL) and is suitable for use with the Pathfinder Roleplaying Game.
