I stumbled on this accidentally and thought I should share:

Peldor is an old Greyhawk oriented campaign website and the fellow who runs it writes up fictional accounts of the adventure sessions.

Glancing through the materials I happened to notice that he had a whole string of adventure stories set in Blackmoor, starting with this one:


The Blackmoor stories run from episode 91 to 100, involve a seedy baron named Albert, a lone tower and fields of undead, a town called Ren in the southwest, and a castle with an unnamed vampire lord. Baron Albert features again in a few episodes starting with number 622. There may be others I haven't come across yet.

The stories are fairly short and a fun read - very D&D. Apparently though they are not all "real" adventures but more fiction based on an old campaign. His take on Blackmoor had a neat feel to it - cool stuff.
