This setting lodged itself into my brain and then never left. One of the most interesting sword & sorcery conceits I've ever seen.

The Planarch Codex is one of the most elegant designs I have seen. It embraces the rich character of the old Planescape and the implications of such a society. It embraces the freebooter; the freelance "troubleshooter" who would be desperate enough to wander across the planes. It explores culture and ethnicity in a thoughtful yet gamable fashion. It's a massive wealth of rich seeds and inspirations to make your games all that much more awesome. It's also free, which is another fantastic point in it's favour. I look forward to the next Planarch Codex.

An amazing toolkit for running Planescape-like adventures with Dungeon World. Until a while ago, my only nitpick was that there was no single-page version available - however, the author has recently filled that gap. Easy 5 stars!

I want to like this product a lot, as it's a great Planescapesque hack of Dungeon World but the format is not easy to use. It's 2 pages a sheet which makes is harder to read on my tablet and impossible to print out as a booklet. Its price is pretty high too compared to other products which offer more flexibility. So while its not terrible the format and cost make me reluctant to give it a higher rating.

A nicely compact gem for Dungeon World, designed to fold out in play into a full-fledged setting. Reminds me of one of those dinosaur-in-a-pill toys: there's not much to see if you're just reading through, but take the advice in these pages to heart and Dis will expand through play.

Two particular notes: Invisible Cities and the "In a Wicked Age" oracles are both tremendously helpful for seeding new parishes, and the Road Wardens provide a great way to keep deceased PCs in the game - while still representing Major Consequences.

I love that the book breaks out all the color of the many many parts of the city (this is basically Dungeon World: Planescape edition) from the mechanics. The sections are all based off parts of another book (that is free): http://collageandarchitecture.com/wp-content/uploads/2012/02/Calvino_Invisible-Cities.pdf

My first grip with this product was that it is laid out in two pages per sheet. Which I find very inconvenient. On the layout front I would add to this the illegible font used for the three major headings and the random approach to page numbering. In this book page numbers seem to crop up at random intervals. Probably more then half the pages don't have one.

Also this is not a settings book. There is no more then the skeleton of a setting here. What there is instead is a poorly organized set of new custom moves for Dungeon World. Note there is no index of moves or any other attempt to make this a useful reference of new moves.

Also absent are any substantial examples of the new moves being applied in play. And really there is so much in terms of new rules here that an example was warranted.

You do get a map with some interesting locations drawn in, but these go mostly unmentioned in the text, and certainly don't get any kind of writeup. Heck even the one Key NPC in the whole book is not adequately described. We get names and powers but no real back story or personality.

All in all Dark Heart of the Dreamer does not compare well to other supplements for Dungeon World. Especially considering that some of the others are distributed free and this one costs 1/2 as much as the core rules of the system.
