I'm terribly late, but I just *had* to tell you how much I loved this! I loved Harry's inner dialogue, I loved the aura thing and the lure of the dark. Most of all, I loved Lucius. Probably for the first time in my life, I actually wanted to be Harry ;)
The ending has me picturing a world ruled by Harry ruled by Lucius. Mmm, lovely image :) I really think I love you! (Or at least your Lucius :) )
