I've been surfing the ICE webring for days trying to answer this question (and bugging Rasyr), so I thought I would try asking here.  Does anyone remember an old shadow world module that details the area west of Rhakhaan?  I seem to remember an old adventure entitled Cynar:  The Cursed Oasis, but I can't find info about it anywhere.

(If you google cynar, you get websites relating to some alcoholic beverage made from artichoke hearts  )

On this page of Brent's webring -- http://www.icewebring.com/ICE_Products/RM1/RM1_1800_Rolemaster_Box.php -- near the bottom of the back cover text, there is the following:

The LOREMASTER Series
This series of campaign & adventure modules are designed specifically for use with the ROLEMASTER fantasy role playing game system. The world of LOREMASTER is dotted with clusters of islands and small continents. Myriad cultures and peoples lie separated by sheer mountains, treacherous reefs, and the powerful but invisible Flows of Essence. Churning like ocean tides under the Five Moons, the Essence ebbs and flows, its eddys and currents dictating unseen barriers and centers of power. Some have learned to tap into that power. Travel across the world is perilous, though some have made it an art: the aloof navigators will transport anyone anywhere — for a fee. And of course, there are the mysterious, saged Loremasters, keepers of the old knowledge and consummate wielders of the Essence. It is they who lead the ongoing fight against the Unlife and its twisted servants. The LOREMASTER Series: THE CLOUDLORDS OF TANARA, THE SHADE OF THE SINKING PLAIN, THE IRON WIND, and VOG MUR. Upcoming Modules: CYNOR: the Cursed Oasis; and THE GATES OF GEHAENNA.

Look at the section in bold maroon. Perhaps that is what made you think that there was such a module. According to a list of old ICE products that I have (which does NOT include MERP stuff), the old ICE never produced such a module.

Most likely, the first edition of Shadow World was created and produced instead...

Another one to add to the "Never Released" part of my list. Although, I need to check that, I might have lost that section in the database version of the list.  I'll have to make sure I keep that page going somewhere.

Not the result I wanted, but thanks for letting me know I'm not imagining things. 

This is what software designers refer to as "vaporware".  It was planned, but never materialized. 

I suspect that in fact it might be easier... As it's an old old old module the choice is limited, they were just starting to hire external authors at that time.

Maybe Terry can give an insight, on who, what, where, how and why.
