So, I just recently read this novel and must say I was a bit disapointed. There were things I liked, such as the framing story about the conspiracy to unseat Gowron (though I don't remember the clone being a good fighter at all in the episode of TNG he was in), but the "history" section of the novel left me with a bad taste in my mouth regarding the twist about the clone being of Morath. The actual story was fine, but the revelation he was not a clone of Kahless really put me off for some reason. So my question is, have other books since this one was published made a mention to this "revelation"?
I don't remember there being any references to the clone not being Kahless's. But I haven't read the novel Kahless, so there could have been sublte references I didn't pick up on.
Oh, it wasn't subtle. That was the whole final twist of the book. The whole thing was about how reality differs from the myth, and that revelation was the payoff. I'm not sure it works, though. After all, the clone's appearance did match the portrait of Kahless we saw in "Rightful Heir."
It was not subtle. The history changes told a good story, but the clone not being Kahless felt wrong to me. I had forgotten about the portrait but that is a good point. One of the myths debunked in the story is that they weren't really brothers.
I believe there's a very, very subtle nod to this in A Time For War, A Time For Peace. Worf is talking about the Emperor then corrects himself to say clone and then says "Even that is in doubt" or something equally vague.
