ok, let see, that's not a new one and the old SW references in RM/ICE products thread is lost in the archive limboes...
The obvious one is Bladestorm. ( no comment )
Next come the little less obvious ones :
- RM Heroes & Rogues... lots of characters that comes from Kulthea.
- Elemental Companion with the chapter 17...
- Sea Law with the chapter 12...
Even more less obvious :
- Time riders with a complete MERP,SW, SM timeline. ( yes you read that... but it's only a page : p62 )
- RMCVI Page 46/47 RM & SW
the RM Improbables :
-Spell Law ( you need the edition with the blue/white/grey pages ) Staff of Agonar ( Agonar is an NPC that appears in Eidolon )
The Spacemaster References :
- Spacemaster Companion ( unnumbered ), the K'Ta'Viiri ( and their stats, first appearence ever )
- Spacemaster Second Edition ( with yet another set of K'Ta'Viiri stats )
- Imperial crisis
- Lost Telepath
( with the famous Heart of K'Ta'Viir and a no less famous V'glin... I let you speculate, in more than 10 years I've never managed to get Terry to tell the truth about that V'glin and the Heart... if you have the book look at it and let your mind wander
)
- League of Merchants ( with Moryn Kaldo and his bodyguards, another stranded K'Ta'Viir and a K'Ta'Viiri ship )
Less obvious :
- All the SM books with a timeline, when a timeline is present it usually reference Imp 450 as the present and set when said present happens in SW timeline.
There's also several references in MERP books, but I haven't opened them in years, but the obvious suspects are : Courts of Ardor, Lords of Middle Earth Volume 1 ( with Andraax in it ), Volume 2 and Volume 3.
