A Two-Round Living Greyhawk Shield Lands Regional Interactive
From the introduction:
The Standing Army needs adventurers to gather information inside of Iuzian-occupied Law’s Forge in order to better plan an assault. You get the job.
This adventure has two tiers: Low (APLs 4 to 8) and High (APLs 10 to 16).
Greycloaks, rangers, rogues, and sneaky people of all sorts should find themselves particularly well-suited to the task.
