Hi all,

I've been trying to figure out the title of a mini-module I recall playing around 1984-1989.  This was some time ago, and the details are as hazy as you might imagine. I'm hoping this community can help me identify it (so that I can re-acquire it, naturally).

Here's what I can recall:
- It was published in a magazine (possibly as an excerpt from a full module)
- It could have been Dungeon, but was much more likely to have been Dragon
- it was a classic dungeon crawl with a light narrative exposition to set the scene
- the main antagonist was a powerful undead NPC, though I cannot recall the name or type
- probably the best detailed clue I can offer is that a cavernous underground river running perpendicular to the progression of the dungeon.  Crossing this river was a memorable challenge.

I've already scoured through the DragonDex - Index of Articles trying to recognize a familiar cover or article name, but no such luck.  Would appreciate any tips or clues!

Bingo!  That sure was fast! The map is a dead give-away.

For some reason I scanned that title and made the assumption this module pertained more to the entire Forgotten Realms fantasy setting (as opposed to a singular, rather small dungeon).

Thanks so much for the speedy response.
