This report caught my interest. Can Windigo be reasoned with? I've always heard that Windigo are incredibly flighty outside of the Hearth's Warming stories.
Yes, they all but disappeared after Weiss's imprisonment. I'm unsure what became of them, but I believe they have, no pun intended, gone underground. Literally, in the sense that their shift to hunting meals without actually appearing to their hosts has made them all but untraceable.
But they can be reasoned with, yes. Their unusual behavior was not always their state of being. Interacting with the Shadow Realm broke them of their bold confidence, making their largest clan grow secretive and skilled at hiding. Anyone would have that sort of confidence with nigh-invulnerability like theirs.
Entry Number Twenty-Two, Day Three-Hundred-and-Forty
Windigo Ectoplasm is an incredibly interesting substance. Generated when they pass through an object with intent, this solidified form of magic rapidly absorbs hatred and heat, freezing the object and saturating the ectoplasm with raw hatred. Once saturated, the ectoplasm becomes mostly inert.
What makes things get particularly interesting is when you trick the ectoplasm into absorbing things in the hate. This is the method we've been using to create Windigo countermeasures. By using careful mixtures of hatred and other such things, we can easily subdue any Windigo that attempts to feed. The easiest method is to simply use a layer of the thickest possible Slumber Syrup. Since it's sedative properties come from magic, mixing the Syrup with Expired Aspira creates a resin that instantly weakens and disorients a Windigo who attempts to pass through it. Like trying to walk through sleeping gas.
Although they can't fall asleep from this, it still serves to sedate and weaken them, to the point where they can barely fly. A bit like the way Turkey can make someone extremely sleepy.
But that's not half as important as the other uses for Windigo Ectoplasm. A substance that can absorb magic, so long as you sneak it in with some hatred, as though you were feeding a dog a pill by hiding it between two pieces of ham. Such a substance has countless, countless uses, across the board. In all likelihood, this report won't even cover half of them. Nonetheless, I'll start big.
By mixing the power of Sombra's Corrupt Crystal Creation into a mass of Black Flames, a control system can be forced into the ectoplasm. This stains the material from it's ice-blue color to a much darker black shade. When stretched thin, however, it turns the most striking shade of blue. Needless to say, my first use for the material was to give it two cute eyes and a mouth. Who would have thought that a magical construct made from domination, hatred, and ghostly parasitic fluid would create such an adorable little critter?
In any case, while it is quite cute, it's also highly explosive to a ridiculous degree. Even a small amount of ambient magic going inside of the fluid forcibly, such as if it directly contacts a magically charged object, is enough to make it instantly explode, and considering it's ability to turn into a balloon by vaporizing parts of itself, it's effectively a balloon filled with very agitated explosive gas.
Even so, I've got better explosive options right now, which makes this a liability instead of an advantage. As such, I don't even understand why these... magically charged chemicals... behave in the way they do. I just don't understand the rules by which magical reagents function, and am left bumbling around and testing results instead. If I knew why certain magics made Windigo Ectoplasm act the way it does, I imagine I could do nearly anything with it, just by combining spells and materials, and then infusing them into the spectral jelly.
In any case, I've still made sure to keep several tanks of this Air Gel, as it's other properties have served well, when combined with basic physics. Namely, the gel's ability to change shape, combined with it's ability to create explosions make it the perfect core for a new generation of simpleminded monsters. By combining the gel with empty metal shells, it gains the ability to use them for structure, and exploit it's own mass as fuel to power internal-combustion devices for added power.
One sad fact is that they still aren't the brightest minions. They are however even more disposable than Wannabeetles, if only because I have a far greater supply of what is needed to create them. Windigo Ectoplasm, Magic that any pony can use, and the new tungsten alloy that my guards have become so fond of. These things combined have given me the opportunity to create a small suite of what I call Knight Slimes. By having the armor ride atop it's fuel supply, I can emulate their namesake while giving the metal knights a massive increase to their fuel supply.
It's as though I've created engines made of gasoline. Powered by themselves and easily fit into metal shells, Knight Slimes are already being deployed in a few locations. Making sure to include cute faces on the actual slimes has improved their approval rating by a wide margin.
Now if only I could think of something to improve their durability, we'd be golden. Then I could start making Metal Slimes. Just imagine the hell of a blob of shapeshifting terminator metal giving you the stupidest fucking expression of goofy joy as it beats you up.
Ahh, what a world that would be.
I must have one. They sound adorable.
I'm not sure that's possible, Princess Celestia. They require Windigo to produce, and... Well, there aren't exactly any around to ask!
Yes, I see. Then there can only be one recourse. I'll look into the matter and notify some of my contacts. If there's one creature in Equestria who can track down anything, it would be... Her.
Who are you talking about Princess?
I'm sorry, Sunset Shimmer, but I'm afraid her identity is a matter of Equestrian National Security. Not suitable for disclosing over our correspondence.
I'm loathe to reactivate her cell, but if she's willing, perhaps it would be for the best, considering how odd Ponyville has become as of late.
Princess?
