Chains of Desire

You've known Princess Elara since forever and now she's disappeared! All the signs point toward the Demon King's castle and you set out to find her like the hero you are. But there's something strange about all this, where are the guards? Where is the Demon King? Why does it smell of cinnamon and vanilla? And why do you hear moaning from behind the door to what you're sure should be the throne room?
