Domination of Equestria - T+15 days.
“You’ve been avoiding me.”
“Have I my dear? Sorry about that.”
“You haven’t lain with with me since our wedding night.”
“Well you can understand, changing a millennia old government doesn’t just happen in a blink. Thank you for all your help by the way, but there’s still a lot to do. The sooner it gets done the better however.”
“There’s less change than you make out. All you’ve needed to do, fundamentally, is move sovereign powers from the established diarchy to yourself. You did that in one day.”
“That may be true, but you know as well as I that the reality is much different. There’s dismantling the nobles, replacing the generals, annexing the cities, and all the rest. It’s one thing to say you have all the power, quite another to actually make ponies feel that power.”
“This...is true. But still you do sleep. I have seen your dreams.”
“Luna, we’ve talked about this…”
“I know, I know. I cannot expect you to remain faithful, or indeed to love me as I do you, but...I suppose I simply did not expect to be discarded so...quickly.”
“Haa…Look, Luna, My Dear, you’ve not been discarded.”
“Yet you refuse to lie with me, and instead prance with...others, in your dreams.”
“Luna, you know as well as I what has brought this on. I’m sorry it has come up so early in our entanglement but I cannot sleep with you as you are.”
“As I am? What do you...Is it because I am in heat? Is this it? It is not I that you find repulsive, but the idea of being sire to my foal!?”
“Calm down Luna. It is not simply you or your foal I have any aversion to. I simply will not be having any foals of any kind.”
“You will not be having foals? But how will you continue your lineage? You are not immortal as myself and the other Alicorns, you cannot rule forever.”
“That remains to be seen.”
“It may be that there are roads to immortality, but none are sure. It would make far more sense to secure your line through the ages, for insurance if nothing else.”
“Heh, no. That’s defeatist talk. If I need insurance against death then there are many better ways to go about it.”
“But what of the joy of raising a foal? Would not a little filly who you could mould into your own image give you joy?”
“I confess, the idea is tempting. But, there’s a bigger problem of them straying too far from my ideals. That’s the pesky problem with independent thought and free will. You can never completely subvert it.”
“That’s never stopped you trying.”
“That’s never stopped me keeping a loaded gun in our bed.”
“Point.”
“No, a daughter would be a bundle of joy and energy to start with, but as she grew up to express the better of our genes she would be so striking a beauty as to gather her own following. Then, when it’s absolutely the most inconvenient moment she would decide that she knows best and attempts to depose me. Or, even worse, she falls to the wiles of some rugged and charming rebellious leader who’s on some ‘crusade’ against the tyrannical government.”
“I cannot sway you on this can I?”
“No Luna, you can’t. There will not be the pitter patter of tiny hooves about this castle.”
“I...see…”
“If it’s any consolation, I’ll rut your brains out for a week once your heat is over.”
“I...I’ll look forward to it, Master…”
Overlord Rule No:19 I will not have a daughter. She would be as beautiful as she was evil, but one look at the hero's rugged countenance and she'd betray her own father.
