Dear Discord,
I was very pleased to see that you'd received the invitation. Finally, my mapmakers had gone to where nopony has gone before, and it seems their rudimentary sketch of the Void Plains had served the postal workers well.
Well, 'rudimentary' is a bit of an understatement. The landmasses keep shifting around so often that they remarked their sketch was just about useless other than to identify the entrance and exit. Their field report also mentioned some anomalous activity there, things like the Black Hole of Endless White, the Upside-Down Rightside-Up Flip-Flop Box, and a flying cow. I've heard of pigs flying, but cows? Now that's ridiculous.
Anyway, I was slightly disappointed with your actions regarding Tree Hugger. I know she can be a bit grating with her attitude and general demeanor--believe me, I've been there with her many, MANY times regarding her obsession with tree conservation. She got very fired up over how an entire forest had burned away to nothing but one tree some time ago. I told her it was nothing--they would come back in due time. I've ensured that will happen, but no, she wants justice for the trees.
"They have been wronged, and deserve proper respect! Are you going to just sit there on your gilded throne and let this travesty go unpunished?!"
You would have never heard a deeper sigh in your lifetime, followed by the second-longest explanation I had to give regarding exactly who is paying for those trees. Namely, me, Granny, and Mayor Mare. The only reason she hadn't heard of it was probably because she was sleeping through the last meeting when I had explained the fire incident. I knew there was no way they wouldn't ask about it, so like a Band-Aid, I owned up to it and got it settled quickly--I paid for the environmental damage, and all of us replanted the trees. There's little left to do but wait now.
As grating as she was, she backpedaled and admitted her "chakras were out of sync"... whatever that meant. Resolved misunderstandings make for odd friendships. Actually, I wouldn't call us friends yet, but I think we're getting there. One day, it'll work out.
That, of course, does not mean you should go off and banish somepony you don't like to another dimension all willy-nilly. Let's face it--you could have done that pretty much anytime before this with me, with Twilight, all of us, but you didn't. I appreciate that leniency, but please don't make that kind of threat again. That's a punishment nopony deserves... not even self-inflicted.
Sincerely,
Princess Celestia
...wait, where's Luna? She normally comes by around now, and the Gala's done and over with...
Aha! There you are! Why are you stuck in the garden with all this smooze?
What? I can't hear you. You have some over your mouth.
I said you have some over your mouth! Gods, is it in your ears, too? Just how did all this smooze get over your head? Did it think your crown was--wait, what am I saying? Of course it did.
Okay, okay... uh, you just stay right there. I'll see if Tree Hugger is still around. She probably got lost looking for the bathroom before leaving. Jenkins will be pissed if she got locked in a closet again.
