Adventures in Varrock/2.15

You miss the chance to kill the dragon, but reinforces come and start tackling it. After it's been killed, the prince(ss) comes up and gives you a huge kiss. You're now a nationwide hero, and this day is named after you for prosperity to look upon in... lookuponiness. You and your newlywed spouse live happily ever after in your private estate on the Lum.

'''Congratulations! You didn't fudge up!''' Oh, that and you won.
