Achilles is cool, attentive, a wise and noble mentor, and one of the only genuinely heroic heroes. Achilles is in charge and will provide information and guidance about the underworld and the gods of Olympus. It is implied that in the past, Achilles was someone very different from the one we know now. Much calmer in his afterlife, he was famous for his Unstoppable Rage and could be a proud and arrogant warrior, like Theseus, but has grown as a person thanks to his time in the underworld.
