The fact that for once I was supposedly going to be the solution rather than a problem made everyone happy. So we finally get to the castle. Think Sleeping Beauty's castle except a little more dangerous with more dragons. Because my character is the key to the problem in the castle, my team had to keep my alive. Which wasn't easy, as a blind low-level wizard is a bit of a liability. But eventually we make it into the castle where we meet the princess.
She was human. And we discover that the prophecy says that her heir will bring an end to the great evil that has enslaved their land. The problem is that the wizard that was causing this problem had made all the men of the land sterile. Now remember, I was the only human in the group. And I was male. I remember turning to Charles and saying, "So for the first time ever in the history of this party I am being called upon to save the day, and all that's being asked of me is to sleep with a princess?"
I had a big smile on my face. I said, "I can do that!"
There's a bunch more to it. We had to get married. And there were some tests. But anyway, we finally get to the point where I'm supposed to sleep with the princess and I'm like, "Now what?"
Charles is like, "You sleep with her."
And I'm like, "But what do I do?"
Arthur—he played the gnome—says, "We were hoping you already knew that."
I'm like, "No, I mean in the game. Do I need to roll a die?"
Charles is like, "I'm pretty sure you can impregnate the princess."
"No, no, no," I say, "I want to see how I do."
Charles looks at me. I say, "We roll dice to see if we can open a door successfully. I can't check if I make the princess happy? She is my wife after all."
"Fine," Charles says, "Roll a twenty-sider."
Remember that in D&D you want to roll high. Twenty is the best score and one is the worst. I crack my knuckles and roll my die. Twenty! I start dancing.
"So," I say to Charles, "I take it she's happy."
"Yes," he says, "So happy, in fact, that she has a gift for you."
She gives me an item called a Wand of Wonder. Basically it's a magical wand that has a random magical effect each time it's used. It's very powerful but highly unpredictable.
