User blog comment:Misakichii/Which Demigod will lead the 7 to the Doors of Death?/@comment-182.68.231.232-20111108191420

I think it's annabeth as prophecy says wisdom daughter walks alone.....mark of athena burns through rome i intercept it as: 1)7th member of quest is daughter of Athena NOT Minerva... probably annabeth 2)mark of athena will guide the quest to doors of death 3) this mark can be seen only by her child which probably refers to walking alone
