Dear Princess Celestia,
I’m writing this letter on behalf of Spike.
Although I enjoy reading in the park with a few cool drinks, Spike is less enthusiastic, and has all but melted into a draconic pile of misery on the library floor.
He hasn’t moved in over a week and his normally gigantic appetite seems to have been reduced to that of Fluttershy’s mice I told you about last week.
So, on behalf of my number one assistant I feel I need to ask, could you please turn down the sun? Just a little?
Sincerely, your faithful student, Twilight Sparkle.
