I do remember everyone who is not sure if I remember them, and I must confess that I do not even remember having two Thingguys or what map you are talking about. I will re-read what I wrote and see if it triggers anything. I had a tendency to just plunge in and not really think ahead too much. :P
[...]The KotOS would launch an assault on the fortress (don't remember what I called it), which would fail miserably until Jonna and Thingguy arrive with the Grammar sword. Jonna wields it, easily containing its power, and becomes the new Swordbearer and basically the most powerful minifigure in the universe (yay feminism and powerful female figures). She succeeds her father Mathias as monarch.
thedude mysteriously disappears (see Rhoddwr Marwolaeth).
KotOS then rebuilds and recruits, restoring life and vitality to Morcia.
End with a quote about "from even the most scattered of ashes the most powerful of Phoenixes may rise."
I did plan this one out quite a bit.
Why is it that everyone wants Jonna to wield the Grammer sword? It's evil! :P And wasn't the sword taken by Brocktree from Sharp?
If we're taking votes, I agree with this too, but I must admit that Wiz is the only one who has ever given backround on the Sword:
"Rise of thedude":
 Now, there was only one thing left for thedude to begin with his plan. The Red Mythrans gave him a kind of steel that was unknown to all else. It was hard and cold, just like thedude wanted it. He took it and forged it into one of the evilest artefacts across the Universe: The Grammer Sword!
Of course, unless something has a will of it's own, it can't be actively evil. Â It could, however be attuned to only those of evil alignment, presenting a difficulty (or indeed, an impossibility!) for Jonna to use it. Also, Wiz has shown a penchant for using 'evil artefacts' in many of his writings, (LotR FTW! :P ) so he probably has a detailed idea of how the grammer Sword works.Â
Basically, what I'm leading up to is, as much as this idea sounds super awesome, I'm not sure the current lore put in place by the only man currently doing Morcia's ancient history will support it. :P Â
