Whether it was the 'spirit' or not, the stated goal of the OP was to have a lore-accurate mod that did not contradict in-game elements. It's not being pedantic, it's reading what was written. If the OP wants what you typed above, that's fine. My original comment concerned the original post, in which the goal was clearly stated - and it wasn't what you listed above. The remainder of the first post was dedicated to asserting that there were insufficient proofs in the game as to the claim that Martin is Uriel's son in the lore. So there was no intention shown of making a mod that is knowingly divergent from the lore - the OP directly asked whether Martin was truly Uriel's son in the game canon, and whether the game had proven it sufficiently.
Given the OP's contention on that issue, it is entirely possible that he thought it would be feasible to write this mod without contradicting canon. Nothing wrong with doing that, but like I said, if any mod alters such a central piece of any game's story, it can't be considered even slightly lore-accurate, and it will definitely be in contradiction with in-game elements.
Ah - I see your point - but I look at it differently - and maybe I am being pedantic because I see contradicting as saying that what someone has said in-game was not said. On the other hand I see suggesting that the speaker was not aware of other events, had been misled or lied may be extracting new meaning or working around what was said. However the reason for suggesting that someone in-game lied etc has to make strong sense (unless the plot requires a weak lie
) in terms of what has gone before or it is disrespectful to the commonsense of the listener or reader - and that may affect the player negatively too, thereby being harmful to the Lore.
If the modder is altering the sense of things he/she should make it clear that he/she is exploring an alternate history. I know people can miss such disclaimers or heads-up. That has happened to me when someone failed to read a Forum Description and took some of my stories as actual in-game Lore (and I had to correct their misaprehension) but it's the spirit and intent of the modder that matters. So once proper deferance is made my way is the modder is then free to make what he can of the Lore.
And I accept that different people see the same thing differently. I've not tried to 'forbid' others to do stuff that was different from my own vision on principal - just so they show proper respect for the original content (and make something reasonably sincere, attractive and interesting) I can respect their way of doing things no matter it differs from the original or my preference, but reserve for myself the right to an opinion as to what I see as best practice and to state that as the way to go.
There is an exception to that. When people working together on a project (even if their stuff is good) start going in directions that are not compatible with the progress of the project then someone has to step up and say so. That's not so much about what you should and should not do, but about eventually being able to arrive at a mutually agreed end-product or at least make some kind of sensible progress.
