1) Harem.
2) Pet dragon (colour/hue/sheen as desired)
3) An old witch who speaks in cryptic metaphors.
4) Fully stocked kitchen.
5) A princess locked in your tower.
6) A moat stocked with aggressive aquatic monster of choice.

You can trade in the dragon for something else if you want; a hydra perhaps. Something big and menacing. Possibly which you can ride.
