You have written well man. Tyrion really lives in this story the dialogue is fantastic.

I am guilt of being a dwarf and now I am guilt of being human...?
-Tyrion Lannister

This is my kind of hilarious. :-)

Lighthearted with just a touch of seriousness, just like the movie, though in this case with a Tyrion thrown in. :)

It does make me wonder though? How would Tyrion react if he ended up in a world like Narnia, he does play the dwarf Trumpkin there though. :D

Anyway good story. :-)

P.S. I would suggest you change this fic to completed if you have turly ended it.

This done not seem like Tyrion because he is a popular noble that is rich and powerful. As we see with his reaction of the threat of the Dragons, he wouldn't be under other's thumb or ignore a threat.
He would seek power of 'an Iron Throne' and rule as a king.
First by keeping his secrets, turn friends into enemies, and hire people to kill threats to his rule.
Then, unite the people under their greed and biases and their hopes to gain more power and followers.
After getting a proper defense, he will start going to change traditions of the people to suit his own goals and build his 'kingdom'.
He may use Human Experimentation when he discovers the cost/benefit from that research and convince thousands of Human/Mutate to go along with it.

This story was much better than I expected given the premise.

What about Sarah Kerrigan (pre-infestation) and a young Danaerys?
