Ok, so I’ve just finished my dual time control/illusion device. Unfortunately, I had to embezzle all of your savings to develop it. Sorry about that. But there’s good news - it can send you back to one of three time periods and let you assume ruling positions.
You can either assume the role of an Egyptian Pharaoh, circa 1250 B.C. - supplanting the role of Rameses II.
You can assume the role of Roman Emperor, circa 100 A.D. - supplanting the role of Emperor Hadrian.
Or you can assume the role of King of England, circa 1250 A.D - supplanting the role of King Henry III.
All positions of great power - you can have your heart’s desire. Harems of the most beautiful women of the age, the finest foods and abodes, power beyond your wildest dreams. Whatever you want - that your subjects can procure. Or you can use your future space knowledge and newfound position of power for altruistic purposes, if that’s your bag.
Or, if you want, I can add additional time periods and rulers to supplant but nothing after 1300 A.D.
The last option is for you to stay in the present without any money. I’ll arrange for you to stay in a shelter until you get back on your feet and I’ll abscond with the machine. Which do you pick?
Since I’m not a total monster I’ll send you back with a copy of Where There Is No Doctor in case you get the royal sniffles - but that’s it. Nothing else from the present aside from the knowledge you carry in your head. All the rulers mentioned died of natural causes so unless you deliberately piss someone off or put yourself in harms way you aren’t going to be assassinated or die in battle.
Oh, I should also mention that the machine includes a universal translator implant, which I developed by embezzling anyone who could lend you a few G’s, so you won’t have to worry about not being understood by your new subjects.
So, should I escape with your savings or do you want to travel back?
Edit: Forgot to mention, if you’re a ladytype you’ll stay that way, although thanks to the machines illusionary powers people will see you as a dude (unless you pick a pre-1300 queen to supplant). Sorry girls, history sucks like that.
