Knightfall
World of Kulan DM
I've been considering getting it for months. I always balked at the price but one of the Acaeum gurus thought it was an okay purchase at that price since I'd more than likely have to pay for shipping from the States if I bought a copy on Ebay.Glantri is a very interesting book because it has the first occurrence of prestige classes for BECMI D&D (and usable in B/X also). I can see why it was listing at $30. It also explains what happened to the spaceship that crashed in Blackmoor and how it will spell the end of the world if the Glantri wizards aren't kept in check.
I'm glad I have it. Plus, it came with an extra cover and a extra copy of the map; although, those bonus tidbits are is pretty rought shape. Still, I could always send them to someone who have the gazetteer but is missing the cover and/or map.
