Only one that iv seen so far is the nemesis shadow shard base if thats the one you mean?
@Damz Find me on the global channel Union Chat. One of the best "chat channels" ingame!
Damz' suggestion is somewhat similar (it's from the RWZ arc, Gaussain's). But i've not found it either...and it's my personal favourite 
Im looking for the grandville map anyone seen it?
Where is that Nemesis Shadow Shard map? i can't find it anywhere!
I would have preferred it for the end of Twisted Tales Part One over the abandoned warehouse I eventually lumped for. I've unlocked all the maps too.
I am looking outdoor Shadow Shard map that appears in some villain arcs.
Does that map exist in MA or not (which would be shame, since it's the most beautiful map in CoX)?
