I wish that were the fact, but officially, they use it as a prime example of why there has to be balance and that balance between good and evil maintained. Basically, they state that when the balance swings so that Good is so far off the scale...it caused the cataclysm. Yep...that's right...Lawful Stupid made slavery, committed genocide, and caused Ansalon to have itself suffer a nigh apocalypse.
ONE of the more foolish treatments of someone's flawed outlook on what Lawful Good actually means.
PS: Now it may be they've retro'd it to be that it now was simply the Kingpriest trying to attain Godhead and his pride, but originally it was a balance issue and used to show what happens when GOOD is so prevalent and has squashed evil...aka...their interpretation of Lawful Stupid...Lawful Good causing genocide, theft, poverty and slavery...
