Ebon Tendrils: Episode 2
A Two-Round Living City Adventure Featuring Low and High Tiers
High Tier/Rounds One & Two: The Quarry of Ebulon
From the introduction:
The Quarry of Ebulon is the high-tier version of The Guns of Azzagrat, a two-round Advanced Dungeons & Dragons Living City event. At the end of four hours, the judge should halt play and allow the players to vote as they would for a normal, one-round event. At the start of the second round, players reconvene with the same judge at the point they left off, and play continues. In order to facilitate easier mustering, both rounds of the Guns of Azzagrat should be played concurrently, though this is by no means necessary.
