classic Greyhawk modules that I need for my collection. Quick to answer was prolific blogger and fellow Midwesterner, Timothy Brannan of The Other Side blog. Thanks to the trade we worked out, I am now in possession of an amazingly good copy of L2 The Assassin's Knot by Len Lakofka.
The Assassin's Knot is the second in the Lendore Isle series which began with the better known L1 The Secret of Bone Hill. I got my copy of Bone Hill at GenCon a few years ago but have never ran it (there's many I haven't). Now with both L1 and L2 I have a pretty complete story line at my disposal that is set in a remote area of Greyhawk which I'm pretty sure I've never used in my own campaigns.
L3 Deep Dwarven Delve was published as part of the D&D silver anniversary collection. I assume it's a continuation of whatever Bone Hill started but this is another adventure I do not possess (great). Len Lakofka also put out another sequel called Devilspawn through Dragonsfoot which I can't count for my collection since it's not in print technically.
The Assassin's Knot will do for now though. I believe collecting is a gradual process so no rush to get them all. I'm very pleased with the RPG trade process. Thanks again to Mr. Brannan and I'm sure we'll stay in touch.
