Taking into account all the translations, it seems to be restoring Ardbert's good name in the First, given he and his friends were blamed for causing the Flood of Light (and thus resulting in the very term "Warrior of Light" becoming demonized in turn). We after all had to take on the alias of 'Warrior of Darkness' simply for this very reason, not they were were actually
wielding Darkness at all despite what the misleading opening movie made it out to be.
So what if our actions throughout the patch story continue to recast Ardbert and his friends in a new.. um..
light... that the people of Norvrandt beging to change their tune about them and what they did, that it was because of them
(specifically, our favourite ghostly-WAR) that we were able to wipe out all the Lightwardens, bring back the night for good, drive out the Sineaters, and destroy Emet-Selch, the one really responsible for the whole mess.
At least, that's what it seems to me (but then, my theories on these New Years' poems always end up being
way off the mark so yeah, take that as just the tired still-haven't-recovered-from-New-Year's-Eve ramblings of a crazy catlady. ;)
