Meanwhile with Cadence

Ever since Cadence had heard from Twilight that Spike had sent a letter to Celestia about the nature of his powers and what she wanted them to do with it Cadence had been in panic mode. Of course she betrayed none of this to Twilight and simply told her to keep an eye on Spike.

The truth was that now there were two major threats to her Master Spike’s harem and her Mistress Rarity’s dream. The first being that one of Twilight’s friends who wasn’t a part of the harem could gain a power that could expose or undermine their little conspiracy. The second great fear was that Princess Celestia would get involved, she was the one who taught Cadence everything she knew about manipulation but still had centuries of experience more than her. If she suspected foul play then things could fall apart very fast.

For now though she and Starlight had gone ahead of the other ponies into the Everfree Forest both to make sure they couldn't get a power to undermine their dreams. And Cadence as noted to herself, her own dreams as well. Her own wish to be the sex **** of her Master Spike and Mistress Rarity. To see herself and the Princesses of hundreds of years experience and immense power and prestige lay prostrate before him. His to use and **** as the sex sluts that they were, but all them lesser than Rarity herself-

"AHH!" She squealed as she felt herself rocked with a mini-orgasm from the thought alone. Hardly enough to sate Cadence endless appetite, but enough to gain Starlight’s attention.

“You alright?” She asked pausing in her steps and looking back to Cadence with brief concern.

Cadence however waved her off. "I'm fine I was just thinking about our beloved Mistress's fantasy again."

Starlight seemed sympathetic. "I know I find those fantasies sneaking up on me all the time. Guess I have you to thank for that."

“Your welcome.” Cadence replied and both shared a small giggle. That was until there was a humming in her pocket. Before she had left she had given Twilight a paper enchanted with a spell, like the one on Sunset's journal, so that she could report on the others.

“What does it say?” Starlight asked.

"They've found two of the roots. The bad news is that Fluttershy has found the Element of Laughter, the good news is that our Mistress Rarity has gotten the root of magic." Cadence explained rolling up the scroll. Happy to see her Mistress gaining the power and influence she deserved. "I'll have to be careful with Fluttershy, but for now we need to find these other two roots."

"Well in that case let’s get exploring.” Starlight said as they continued to explore the forest. Each attempting to use their magic to detect the crystals that seemed to form outside the caves.

“If only there was some kind of pattern.” Starlight admitted tapping her chin in thought. Cadence agreed but suspected that there wasn’t one. “Or a spell.”

“Hmm maybe.” She casted a spell they used at the Crystal Empire to detect magical crystals. It had been used to search for any remaining tricks Sombra may have left behind, but now maybe…

“Bingo.” There was a faint trace of the same magic that the elements of harmony were made of, just a few meters away. “Found something this way.”

She ran in said direction with Starlight following closely behind her. Sadly the spell was limited in range and she could not scry the whole forest. Fortunately this root seemed close enough.

They came at a stop by a pond, not the mirror pool thankfully.“The cave is underneath the pond.”

“No wonder we couldn’t find it.” Starlight said examining the pool. “So what do we do? Drain it?”

“Hardly.” Cadence answered before stripping herself bare in the forest. Letting her hourglass form be there for any passing stranger to see, her huge tits to swing from side to side, as she tied her hair back. “Alicorns can hold their breath for a long time.”

And with that she dived into the icy cold water, swallowing her disgust as she made her way through the mossy greenish pond until she saw the cave she was looking for. Swimming to the surface, and carefully climbing out of the water. Taking great care to avoid slipping on the wet crystal floor as she approached the cave. To her delight she found exactly what she was looking for, one of the Roots of Harmony, this time with a picture of three butterflies plastered on it.

"I suppose this has to be the kindness root." Cadence said as she approached. As she expected a holographic image of Fluttershy appeared before her. Hands fidgeting and eyes hidden behind her long mane. "And you must be the Element of Kindness then."

"Um yes that would be me." The Element of Kindness admitted, her voice no louder than the actual Flutttershy. Enough that Cadence had to stretch her ears in order to pick up exactly what he was saying. "You know what I am?"

"We were looking for you and the other roots." She admitted to the Element of Kindness. Cadence took the opportunity to with the trained eye of an alicorn examine the hologram. Definitely wasn't a common magic hologram, it was much more detailed than a normal one. With a sort of hexagonal crystal texture, seemed more advanced than any that Cadence had seen before, even from the likes of Sombra or Starswirl with a sort of glimmer to it like diamond.

The Element of Kindness looked surprised at this answer. "You knew came looking for us? I suppose you know about the powers then?”

“Yes. We wanted to keep them out of the wrong hands.” Cadence lied, she was under no delusion that her hands were the right ones. The Element of Kindness seemed skeptical however.

“Are you sure you’re using it for the right reasons?”

“Of course I am.” Cadence answered resolutely, whatever morals she may be trampling on, she was committed firmly to being a sex **** to Spike and Rarity. The Element of Kindness relented.

“This power isn’t as flashy as the other elements.” The Element of Kindness explained with a gentle voice. “But I think it’s very useful in order to be kind.”

“I’ll be sure to use it that way then.” Cadence lied with a completely straight face.

"Well it's often a challenge for when you're trying to be kind to know what a pony wants or needs. To know exactly what's upsetting them or when they only pretend to be okay but really want your comfort. As such your new powers will let you read the minds and emotions of your friends so you can help them whenever they need your help." The Element of Kindness explained in a sort of naïve optimism. "Just be careful and you'll be able to always know just what to say to comfort to anypony whose upset."

Cadence was barely holding back a grin of delight as she could feel herself granted the power. It was easy to master, as easy as if it was just another limb on her body. Casually she already began to scheme of all the advantages this power would give her, what edge this would give her over Celestia. What weaknesses she could find in potential recruits for the harem.

"Yes I'll be sure to use this power wisely."

A/N: I'll admit here I'm hesitant about which to provide the next two roots of harmony to. While I've heard several good ideas I have to admit there's not many I've absolutely loved for loyalty and generosity and would really appreciate any suggestions. If not I'll figure something out. For convivence's sake I will list ideas for the Elements of Loyalty and Generosity here though I'm open to changing them. Just don't make it so powerful, they don't all need to be as powerful as the Root of Honesty.

Loyalty: The pony with this power can change a person's loyalties not just to themselves but to others. So they could make a pony loyal to Celestia loyal to Luna instead for instance.

Or as an alternative the bearer of the root of loyalty can designate a person as a 'leader' after which all members of an group becomes completely loyal to a leader. So for instance Pinkie could be designated as 'leader' of the pie family and they'll all become fanatically loyal to her and do whatever she says.

Generosity: This one I'm weaker at. So far I've only got that this allows one to both give and be given not just physical but ideas and what's impossible to give. Like bust size, skills, and stuff like that. Ponies would also become much more generous to the wielder.

Any ideas here would be more than welcome.
