Nothing like playing up to player imposed stereotypes that don't have any proof behind them. Also, given the way the paladin 'protection' quest works, it seems that its standard operating procedure for the paladins to do a detect evil/alignment spell with anyone they are having dealings with. Also, I'd think that the Radiant Heart would want to try to verify Garen's story through some other means if they had any doubts. I'd have to say that with what the game gives you, trying to shoehorn another explaination around the circumstances seems a bit awkward.Any number of ways... they're noble, and thus extremely stupid
The writing is great, but I'd have to agree with Hendryk that a different reaction could be more appropriate on Garen's part.
But regardless of your decision, keep up the great work. I look forward to the eventual day that I can play your newly released mod as I lie on my deathbed.
