Two Dark Towers -- a clarification

 So, 

Looking at the title of my recent post it occurred to me that I might have been inadvertently obscure in my references.

To clarify: DARK TOWER is a D&D adventure, written by Jennell Jaquays, released by Judges Guild in 1980. 

 THE DARK TOWER is an unfinished novel by C. S. Lewis, written circa 1944 but not published until 1977. 

I contributed an appreciation to the recent deluxe edition of DARK TOWER. Years ago (1996 I think) I wrote a piece detailing THE DARK TOWER's origins.

Sorry for the potential confusion.
