Dear Spike,  
___It’s been ages since we’ve seen each other. How are you? As you’ve already guessed, I am still trying to find a way to thank you for your assistance and generosity. Again, I wouldn’t be the dragon empress if it weren’t for your kindness.
 
However, I am only left to think about what would’ve happened had you remained the dragon emperor beyond the thirty seconds the scepter’s powers flowed through you. Now I can’t even imagine my place being infested with Garble’s muttering and talk about conquering the ponies. But I digress.
 
I know that you want to know more about the dragon kingdom, and I’m writing to you to inform you of another one of our customs. It is currently the eve before the mating season, and I know there will be urges that will flow through you and transform you into this wild, incredible, strong, sexy, firm-tailed totally different creature. And you will want to assert your feral dominance over your mate.
 
It’s normal. It’s kinda scary to go through that first season and feel yourself itch and burn in places that you’d never thought of scratching. You know, precious scales are best left unscratched by one’s own claws. But I can assure you that it would be perfectly fine to talk to me if you ever felt that way.
 
Spike, my friend, I wish you to know first-claw of this experience and how it changes you for the better. I’m doing this because I know that it will confuse you in the future if it goes unchecked. And when that happens, you do bad things to others around you, to the ones who trust you. And I know you don’t want that.
 
I’ll be migrating to Ponyville as this letter gets to you. If I had timed it correctly, it would mean that you would be getting this upon the sun’s setting and the moon’s climb. You will be in your room by the time, and probably doing pony stuff. When I arrive, it is best to establish a small nesting area so that I may find my accommodations to my liking.
 
See you in five minutes.  
~Her Imperial Majesty Ember.
 
P.S.: Just unlock your window. I know where it is.

Dear Spike,
 
First off, thanks so much for these quills and ink. Never going back to charcoal.
