No reason to beware the Ides of March this year! Frandor's Keep was waiting for me on my doorstep when I arrived home today, two days earlier than its scheduled release date. I already begun to delve into the book and I am quite impressed with what I've found. The maps and the details of the Keep and its inner workings are fantastic. I'll post a longer review when I've had a chance to read through the whole book, but my initial reactions are very positive.
There are a number of previews and bonus downloads available through Kenzerco's website so head on over and take a look for yourself. The Keep map in particular is great and will really bring back memories for those who loved the original B2: Keep on the Borderlands and the map of the Keep found therein.
