Ace 3.1 - 03–25 Storming the Diamond Gate

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 was really well done. I was surprised our GM was first time GM'ing for PFS.
