You don't think you've ever run so fast in your life.
Dropping everything that wasn't already in your bag, you take off at a gallop as you transition into flight that takes you out of the diagram in a flash.
And not a moment too soon.
The earth itself lurches, knocking Cobalt and Brynn from their hooves as they back away from the diagram. You float over to where they sit as the earth shudders and quakes, the three of you unable to peel your gaze from what's happening inside the diagram.
The lines themselves are shifting, changing from piles of dirt to streaks of blue energy that lash against the ground. Frayed ends where the dirt was disrupted thrash wildly, one entire side disrupted.
The circles change colors and become green ellipses full of a rainbows gallery of energy, all of it pulsing in a rhythm akin to a heartbeat.
Some of the ellipses turn red, and collapse, suddenly fading into nothing but scorched ground as they fail.
The mannequin, still on its side, rises into the air and slowly spins. It's no longer upright, but is intact for the most part.
"WHAT DID YOU DO!?"
You and Cobalt turn to look at the unicorn, who stares in wide eyed horror at the scene unfolding before him.
"He did as I asked. He stopped you." Cobalt replies coldly, turning from Brynn to look at the wild display of raw energy and colors taking place in the field, "And he did a darn good job by the looks of it."
Brynn shakes his head slowly, trying to say something. But no words come out. Not until the blue lines of the diagram suddenly raise from the ground, angling toward the mannequin and rising to meet it, dozens of lines flowing from the ground toward the mannequin.
"No," he finally says, "He didn't stop it. He changed it! HE CHANGED IT!"
He opens his book, suddenly flipping through pages of foreign characters and drawings, each page covered in a myriad of notes and half finished translations. Finally, he settles on a page, rapidly reading something to himself as you and Cobalt share a concerned look.
"What did he change it to?" Cobalt finally asks.
"I'M TRYING TO FIGURE THAT OUT!" Brynn screams in frustration, flipping through more pages and reading aloud, "Blue lines! Myriad of colors! Beneath the full moon will she rise, returning to….Oh….oh no….."
"What is it?" Cobalt says, moving over to try and read over Brynn's shoulder, "Who or what is being summoned?"
"Leifjka Neferat," Brynn says, reading from the page and swallowing nervously, "Heir to the Forest."
"Heir to the Forest?" Cobalt says with a slight grin, "That doesn't sound so bad!"
"Which forest do you think she's in charge of, Cobalt?" Brynn says slowly, "Here's a hint: You aren't far from it."
Cobalt's smile fades.
"That's right," Brynn says as he shuts his book, "The Everfree. Unable to be controlled by pony-kind for as long as anyone remembers. Filled with monsters and dark secrets."
He stands slowly as the quakes in the earth subside, a bright green light suddenly stretching between the mannequin and the cloudy sky above.
"And she comes. Untethered to anyone."
"What do we do?" Cobalt asks, rising as well, "What CAN we do?"
"Someone has to stand in the light, I think," Brynn says slowly, thinking out his process, "I cannot. I don't know what will happen exactly, and I have the two tethered to me to consider."
"Then one of us has to do it," Cobalt says, looking at you.
A moment of awkward silence passes, before he finally says, "I'll do it."
