Dwarves and a marvellous sword and sorcery premise, its a marvellous contender in my book! and my book isn't the book of grudges! Longer room descriptions but well within manageable prep, especially being a no-nonsense 9 room layout. Interesting and unusual mapping style that lends well to theatre of the mind (I assume most tables play knave theatre of the mind rather than a grid) and It has given me endless inspiration for designing my own dwarf hold for my ongoing campaign.
