I have received Keep on the Borderlands as an early Christmas present. I was quite surprised how just flipping through a few pages and scanning a few maps fired my imagination. This is partly because my copy is in pristine condition and largely because of the quality of the product.
I'm currently in my home town, and next week I'm supposed to run three sessions of D&D for my old gaming/high school buddies. Originally I was going to run a homebrew adventure, but now I'm dead set on running them through the Caves of Chaos and the surrounding wilderness. I've never run this module, which as I understand it means that I haven't completed one of my OSD&D rites of passage. I aim to rectify this.
The module itself is, from my skimming, broadly compatible with the World of Nightwick. So far I've just had to change the word "Elf" to "Changeling" in a few places. The biggest change I will be making to the module is designed to accommodate my take on Orcs. Since they don't breed normally, I have removed non-combatants from those caves and replaced them with a rather nasty surprise for potential delvers. Otherwise the caves will go untouched since the other humanoids of the World (at least the ones in this module) do mate in the usual fashion. I may replace the Kobolds with Mites, but I may not.
I'll post play reports and development updates here. Hopefully I'll be able to give you a good dose of behind the screen information in both. This will be my first time running a TSR D&D module. I'm very interested to see how it goes.
Wish me luck.
