You see a beautiful, 400 ft tall dragon with five different colored heads and wings that seem to span for miles. The energy coming off them is immense, their scales glow with goldy power. They are laying on a massive hoard of gold and gems.
I whisper "The Dragon Goddess, she's incredible."
Thank you for your kind words, mortal. I am the goddess Tiamat, ruler of all dragons and keeper of their treasures. It is not often that one of my mortal subjects pays me such a compliment.
I get on my knees and lower my head to the ground, blushing "You're words are wasted on an insignificant mortal like myself."
Rise up, my humble admirer. I did not mean to make you feel insignificant. In fact, I find your admiration quite flattering. Tell me, what is it that you desire from your divine goddess? Is there anything in particular that you would like to ask of me?
Or perhaps... you wish to offer something in return for my favor?
I rise slowly, my face still red "I offer you my life, my soul. My deepest devotion for you and you alone. I... I'm not sure what to ask from you."
Very well, mortal. Your devotion is most appreciated. As your divine goddess, I will grant you a boon in return for your offering. You may ask me for anything within my power to grant. However, know this: once you have made your request, there can be no taking it back.
I nod in understand "Then... I desire a family. I wish to be a husband to a beautiful wife and a father to many children"
Very well, mortal. As your goddess and in exchange for your offering, I hereby grant you a family. You will be wed to the most beautiful dragoness in existence, and together you shall have many offspring. They will be strong and wise, just like their parents. This gift is mine to give, and no other being can take it away from you.
I blush "Thank you Tiamat!"
You are most welcome, my humble mortal. Now go forth and enjoy your new life with your family. May they bring you happiness and joy for many years to come. Remember that I am always watching over you, and if ever you need my aid, do not hesitate to call upon me.
