Dear Lady Sunset Shimmer,
I am writing to you to let you know of a little reef known as Sea Ponies Paradise. It is located of the coast of Hoovstralia just south of Brismane. it is also not very far from the home of my cousins who live in the under water kingdom of Merstralia. which coincidentally is of the coast of my home the beautiful island of Aurora Eponialis.
I do not know if you have heard of any of these places with your sojourn into the human world through the magic mirror portal.
my dear friend Twilight Sparkle the Princess of Friendship in Equestria told me of your run in with the sirens from another underwater kingdom known as Aquastria. if they can return to their native home it would be better for everyone.
now I know you maybe questioning my sanity right now in regards to that but please just hear me out. From what twilight has told me their heart stones were destroyed when you and your friends conjured the Alicorn Goddess Harmony Rainbow. these were the source of their wicked negative emotion producing powers. these cannot be replaced as the magic used to create them and transform the girls from ordinary mermares into sirens can only be done once.
the girls will not be able to survive long without these heart stones in the human world as they have been living on borrowed time due to the magic the stones produce. in order for them to survive and learn to live as they once were and truly learn the magic of friendship they must return to Equestria at the very least.
I have come by this information through my cousin Amerthyst Azure who is a princess in Merstralia. she did say that as Aquastria is now ruled by King Leo the Sea Lion, Adagio, Aria and Sonata will not be welcomed back there. however they are being offered a place in Merstralia if they choose to accept it.
this is why I have given you the direction of where Merstralia is located and the beautiful places that surround it as that is how to get the ex-sirens from Equestria to Merstralia. the sea ponies who live in the lush sea pony paradise have agree to guide Adagio, Aria and Sonata to Merstralia.
I hope that this is helpful to you and that I am not asking too much of you to help the girls out by getting this message to them.
Your friend hopefully,
Princess Katmare Sparkles Ruler of Aurora Eponialis
