Hades heard Apollo in the distance, for being surrounded by the screams of agony and pain and death in the underworld his whole life, wow can he hear, and he looked directly in Apollos direction, "Dreadful, my Nephew, you not even Know the Meaning of the word, its more, hmmm, whats the word, My Zeus, oh that's right, Horrifying, than it is Dreadful, you should come down for dinner sometime." He laughed at his crude humor, he knows that anyone to part take in eating any food of the underworld would be trapped there unless Hades wills it, that was the only reason how Persephone was able to come up to Olympus ever 6 months.

A Wraith, one of Hades' creations of the Underworld came up to him and whispered in Hades' ear, Hades looked at the Wraith and flared as steam escaped his Helmet "A MORTAL DID WHAT!!!!" his voice in Anger echoed throughout Olympus, and it was enough to make (pardon my french) little Cupid shit his diaper and hide behond his mother Aphrodite. Zeus stood and walked down to his Brother and asked What was wrong, Hades turned to his Brother "A MORTAL HAS ENTERED TARTURAS!!!" Zeus' eyes flared causing Thunder and Lightning to strike and flash. 

Deep in the Underworld a mortal fool had Foolisly walked into the Prison of the Titans, Tarturas. It held some of the greek titans, but the most powerful was Gaia, the titan of Earth. She had most likely summoned or called to the mortal with what little power she had in store, she knew this mortal could help her with proper persuasion.
