A very insightfully-written adventure which plugs in a lot of questions I had after going through the first chapter of Descent Into Avernus.
The tact that went into filling in the details here is exemplary...truly a masterclass level of 5th-edition adventure design. My favorite (and possibly widely under-appreciated) feature is the larger font size, which makes each page easier to digest and run on the fly.
Shield of the Hidden Lord is worth more than the listed price. There's plenty to chew on in here!
