Nice work. Nothing much wrong with it that I can see.
One suggestion I would make is that you list the skills in a different order, or group them into categories. The impression I get reading down the skills page is that it's rather combat oriented. The first sign of a non-combat skill is a long way down the page. You could use subheadings, so that the reader sees "Combat skills", and therefore knows immediately that there will be a significant number of non-combat skills.
Personally I think I'd go for a different order. The most interesting and informative skills are the non-combat skills, since everyone knows there'll be quite a few combat skills. Seeing "Dagger, Sword, Axe, Hammer..." doesn't really tell me anything interesting about tAoD; seeing "Persuasion, Etiquette, Streetwise, Lore" tells me a lot more.
Speaking of which, one or two minor points on wording etc.:
I think Etiquette should read:
"...how to apply them to your benefit." (not benefits)
In Lore, "...of the events long gone..." sounds a bit odd to me. I'd say "...of events long past..." is better.
In Trading, I think "...commerce matters." would be better as "...commercial matters." or "...matters of commerce." or alternatively re-phrased. I can understand preferring "commerce" over "commercial", but "commerce matters" seems a little odd/wrong.
One question on the overall story:
"Now the player is given a chance - it's optional - to piece the original story together, by comparing different accounts and looking for earlier records, trying to separate the truth from the myth."
Does this mean that the absolute truth of the past is set in stone within the game world, and the player must separate the facts from the myth (and be either right or wrong in his conclusions); or does it mean that there are various possibilities of what might have happened, and that the player must decide for himself what he believes to have happened (but not be objectively right or wrong)?
Basically I'm asking whether you have a clear and certain idea that X, Y and Z happened, and that is THE TRUTH(tm), or whether you admit a range of possible pasts.
I guess I'd prefer things to be indeterminate, but mainly I'm just curious.
