Pieces liberated from "Dark Tower". Get that in the original version for an AD&D classic module. Honest in its text - written by a 13 year old - and not in a good way. Don't waste your time unless you want to point and laugh at it.

This feels like old school in the best way. It has a sketch book style. Break out the graph paper and gather a few friends and have fun :)

The typewritten parts are from JG088 Dark Tower by Judges Guild in 1979. The "Gems of Fire" refer to the 6 "Soul Gems" which are artifacts in the JG088 module. In that module, the gems embed in the forehead of the person who touches them. They are intelligent and try to possess the will of their new host to follow strictly the alignment of the gem.

I think you'll find the cut and pasted bits are from "Dark Tower" by Paul Jaquays. As for the additions and the map, only if you're far, far gone in nostalgia.
