This is an excellent introduction to a setting and campaign that grabbed my interest so quickly that I bought Rising from the Last War, began to do an Eberron deep dive of my own, and now plan to run the entirety of Oracle of War as it's released.
Truthfully, I think it's the little details in the way this and the other released adventures are structured ("Legacy Events" that provide meaningful in-character feedback to player choices; in-game newspapers that connect characters to the world) that makes it so brilliant, and while I know some experienced DMs could create things like that on their own with any other campaign, I wish all 5E releases would incorporate the quality of writing and design elements that Shawn has done here (the brief list of personality quirks and quotes for newly introduced NPCs is a super-helpful touch for DMs as well).
In short, a fantastic introductory adventure that hits on all three "pillars" of D&D design (roleplay, exploration, and combat), introduces players and DMs to a novel and intriguing setting, and makes me genuinely excited for the rest of the campaign to come. Please keep these coming!
