This AD&D (2nd edition) book is an in-depth examination of that pillar of fantasy literature - Dwarves. It has chapters on dwarven mythology, subraces, sociology (so you can better understand how dwarves think), character creation, proficiencies (26 new or specialized ones), kits (24 new ones!), personalities, mining (complete with rules for running your own mine), equipment, strongholds, and designing dwarf campaigns.
Yep, this fantastic book has it all! If you run an AD&D dwarf character, or you are just interested in new kits and ways of running campaigns, then I highly recommend this book to you. It is definitely a must-have for AD&D (2nd edition)!
