From the introduction:
A 1-round Advanced Dungeons & Dragons Adventure for 6 - 8 Characters set in the Forgotten Realms.
Half an age ago, when the world was younger, so was Elminster. In fact, he was a green and careless adventurer. Whilst exploring a mage's tower, he left something behind... something that, it turns out, is very important to someone. Someone who will destroy kingdoms to get it.
There's not much left, now, of the mage's tower—only its upper half survives, floating in midair. There's also, after all this time, very little left of the mage... or is there?
This is an AD&D Forgotten Realms Adventure for 6-8 Pre-prepared Player Characters, the Baron's Blades adventuring band.
