Royal Twins

When did the Royals begin engineering the birth of twins, even triplets?

It led to a alternate world in which the twins could be safe, not known publically as a twin, and of course, never allowed out of the alternate world without schedule. It could all be closed down by a staged death, or real one. But the Royals lived two hundreds years...the last one hundred a bit loony on cloned organs, brain meds and stem cell injections.

Even then, when the willfull royal would revolt and disregard the rule, the other twi outside, was notified, and never have they failed to drop quickly out, by way of a sudden plane flight even.

Furthermore the control of photographic access, the restrictions of press, enhanced the practice of twin birth, while announcing a single child as born to the public. At least, how the story goes.

So, this alternate world created was ever a curiousity to me, in so being severed from public understanding, those technologies, exotic, advanced, powerful...drugs, vehicles, architectural playgrounds, privileges and privacies, not all deployed in great decadent expenditures?
This only to them, those beyond public, beyond private, locked in gilded cages and subjected to scientific study? Or, in fact, sprawling across the Solar system in various styled moon colonies around various planets.

Lets consider Hans.

Hans owned a restaurant. That is how I knew him. Well, Hans twin was there when Hans twin was in wonderland.
The real Hans was found dead, though, killed by inhaling Poison Ivy.
Urisol.
Of which I am afflicted myself, a common weed around here. Horrible way to die, by the way.

I also have a double. However, this double has never left Wonderland.
He writes me letters, describing it, in the name of Dave Wilson. Should I believe him? He sends me pictures of myself doing things I have never done. And, those pictures...look like they are from moon colonies.
Dave wanted to know what happened to Hans, and so I went by and found out.

Sometimes we twins know each other, sometimes we don't. Sometimes a double never leaves Wonderland, and the royal on Earth never knows it exists. Some twins are evil, and mine, in Wonderland, I am beginning to think, is in fact profiting from the destruction of my life.
Or, maybe I am just paranoid.
I just figured it, and in answering my twin, I learned in our case, the case where the twin doesn't ever leave Wonderland, is extremely rare, and also, it is even more rare that the other Twin, me in this case, finds out. In fact, Dave told me there is only four of us, two in China and one in India.
Otherwise I guess the ground Twin is kept too busy.
Nose to the grindstone.
