Last Days of the Demon King

As long as memory serves, the land has been controlled and owned by demons from other realms. Is this all there is to our existence? How long can our Kingdom suffer such abuse? They don't belong in our land, they invaded through the corrupted magic of an idiot King! Where are the ancient heroes? No one has come to save us through the centuries of slaughter, I don't see anything changing...ever. There are those who still whisper of ancient Gods looking for a fight, or a world to cleanse. We continue in our demonic slavery, hoping beyond hope they find a way into our world through the same vein of magic the demons entered. If someone doesn't come soon, there won't be anyone left to save anyway, demonic entities appetites cannot be curbed.
