What do they do? Are there any examples of them in the story?
The only thing I assume at the moment is that attaching to/entering the Dream uses the Mind Domain.
One of Mordremoth’s sphere of influence was the mind. Now that he is dead that will be being absorbed by the other dragons to some degree or another.
For shadow: There’s a lot of darkness themes throughout Orr and risen related stuff, but it never held a direct role in the story. The closest would be the greatest fear arc where Zhaitan directly or indirectly makes you confront your greatest fear.
For mind: All Elder Dragons have some form of hive mind with their minions, but this isn’t telepathy by all indication. The most the minions get is a sense of the dragon’s will, from what we’re told (though without direct examples hard to say) – Glint’s telepathy is made to sound unique, after all.
Meanwhile, Mordremoth not only has massive, individualized, simultaneous telepathy but he’s shown capability to transferring his mind across his corruption (as he did with Trahearne). I’d chalk both of those up to his domain of mind.
