Dear Firelight,
I am writing you to let you know that Starlight's time has come. She has done so much good to help Equestria including saving us from Chrysalis and the pony of shadows. She has helped Twilight so much by giving her good advice and calming her down when she has her meltdowns that she is truly deserving of this.
Sincerely,
Princess Celestia
Dear Princess Celestia,
Really, Starlight's time has come? I am so happy that our little angel has finally done what needs to be done to fulfill the destiny I knew that she has always had. Now I do have some advice, don't let the other one take over because I have my concerns that she will throw Equestria's borders open to outsiders.
Sincerely,
Firelight
Dear Starlight, Trixie and Twilight,
Starlight, your time has come. A very powerful pony is on his way to Canterlot to do for you what the big brass would not allow me to do. Not only will you be ascended but so will Trixie and to make things even better, your father will be here AND so will your mother. Yep, you will finally get to meet your mother. She is kind of anxious about how you will react because of how she had to have Firelight raise you but just know, she does love you and is anxiously awaiting the arrival of you and your great and powerful soon to be wife.
Sincerely,
Princess Celestia
P.S. Oh and Twilight, you need to come too because we have to have a discussion about your future role and whether I will let you take over or not. As you know, the visions I saw in that crystal ball do bother me and I do need to know what your real plans will be for Equestria should Luna and I actually decide to retire.
Dear Princess Celestia,
Really? I'm finally going to get my wings, I'm finally going to get to meet my mom and I'm probably going to get to marry Trixie? You have no idea how happy I am. This is something that I have waited for for so long and it is finally going to happen! I will admit, I'm kind of nervous about meeting my mom but I know you wouldn't lie about her loving me so that does make things a bit less stressful. Trixie and I are so excited to get up there so our destinies can be fulfilled.
Sincerely,
Starlight Glimmer
P.S. Princess Celestia, you aren't going to let me take over, are you? You're going to wind up being a conniving, backstabbing, lying bitch aren't you? I should have known that you would deny me what is rightfully mine. I will come up there but just wait you treasonous, cake craving glutton, I will depose you before you can put your precious daughter on the throne and begin a new glorious era of Equestria, a more welcoming Equestria....one where ponies aren't viewed as superior to other creatures and we won't have anycreature starving because of a lack of bits.
