Lucifer's Rebellion (HELL)

"Demons are real!"
'Yan ang tumatak sa isipan ni Demeter matapos niyang makilala ang pitong prinsipe ng impyernong sina Beelzebub, the god of Envy; Sathanas, the god of Wrath; Abaddon, the god of Sloth; Mammon, the god of Greed; Belphegor, the god of Gluttony; Asmodeus, the god of Lust; at ang panghuli'y si Lucifer, the god of Pride.

What does they need from Demeter?
What will she do after she had bumped with them?
How would she deal with them?
