This absolute work of art is quite possibly the best setting book available for D&D 5e. Eberron is one of D&D's most robust settings and this book did it the justice it deserves. If you're looking for the deep lore of Eberron as well as more, Eberron specific, character options then this is your book. Honestly, anyone looking to run full campaigns in Eberron should highly consider this product as it gives DMs the tools they need to truly become lore masters at the table. I also find it to be an incredible world building resource. It is the best example of a fully fleshed out world brought to page and gives homebrewing DMs something to aim for. Quite truly, my only complaint is that the Hardcover doesn't sit flush with my other 5e books but that is hardly a complaint at all.
