Mysterious Letter

There's an odd letter sealed with a green wax stamp depicting a dragon in your mailbox. The following was written inside...

'Hello, friend. Have you heard of the Archipelago? Of course you haven't, we get nary a visitor in these lands. Though, I have heard of your world, so drastically different from ours. You see, you and I, we are not from the same dimension, of sorts. There are numerous differences between us - most notably, that mare, Twilight Sparkle - she does not exist in our world, nay. Instead, we have a corrupt poser who drains the most powerful beings in Equestria of their magic - yet, we remain, far outside Equestria, in our own nations, safeguarded from Twilight Nebula and her dogmatic ramblings. Allow me to tell you a story...

I was once known as the dream herald. I granted wishes to children, protected those in need of it, I was the guardian of a continent. Yet, those times have come to pass. I understand your Twilight saved the world, yes? Ours didn't. Her ascension was... Premature. I've been studying your world. These beings, Discord, Chrysalis... They've never existed in my world. Twilight's ascension has crippled them, altered them to the point where they're too weak to rise. The powers at play are different here. I've seen it all. I'm older than anyone else. I've seen civilisations come and go, leaders shift and great wars, yet nothing strikes me as peculiar other than that one mare, the one-winged alicorn, Twilight. Not long ago, only forty years or so, she fell into a deep coma. Her unbridled magic tossed the world's path out of order, muffling the magic of the strongest beings alive - except her own. I remember in the last moments I had my full power. I remember that magic wave coming toward me. In a final blaze of glory, I hoisted my claws up to the skies and wished that what all the ponies prayed to, everything they believed in and all the mythology of the archipelago, for it all to become real. That was my last granted wish. Hope. A wish for a savior. I've come to understand your Twilight is not a merciless brute. How do I know? With age comes wisdom, and lets just say I've been alive for a long, long time. While your Twilight may save the world time and time again, ours has long since abandoned the ways of friendship and elements of harmony as a whole. A cruel tyrant, she is - I'm glad to reside far away from her cold grasp. Now, you may wonder, what exactly is the archipelago? Well, it is our great homeland, a huge continent of speckled islands and nations, species and cultures, and all with a destiny of their own. Whether it be Palisade's protection of the south, The Order's unification of the nations, a mother's duty to raise a righteous child - we fight for what we believe in. Though some resort to violence, I assure you, it may not be as bad as you perceive it to be right now - we are humble, welcoming people, and we are open to all that seek our guidance. If any of this may interest you, why not pay me a visit? The seal on the letter is imbued with a special kind of magic, that'll transport you to me straight away. But, immortals and heroes, remember this - here, you are mortal. Yours truly A future friend.'
