"Let's go over what we know for sure, one more time."
"Right." Twilight cleared her throat. "We know there's a version of Equestria that's ruled by Nightmare Moon, accessible through a Behemoth scale. We know experiments are being run in her castle, which appears to be the old castle in the Everfree, seemingly for the purpose of creating some sort of weapon or soldier, and the results paint a clear picture of how they treat prisoners and others who oppose her. We know that they may have noticed our presence there at some point, and we know that they have found a way to reach our world without using scales."
Celestia nodded, and so did Luna's image through the enchanted mirror on the wall. "How is progress coming along on a way to stop them from coming here?" the latter asked. 
"Preventing them fully from entering our world with a spell on this side isn't really a possibility at the present moment. The best we can hope for is a type of shield spell that might prevent them from teleporting to certain locations, but of course covering the whole of Equestria with it isn't feasible. Smaller, more focused applications are the current plan." Twilight shifted her notes about in her magic, without actually looking at them. "However, without analysing the exact process by which they're coming here, research has come to a halt. There's only so much we can do with just the landing craters."
"So the plan is to go in there again," said Celestia.
"It's a necessity," Twilight explained. "If we don't act soon enough, it might be too late once we do."
"But it is a risk," Celestia continued. "Someone might be spotted there. Worse, someone might be captured."
"But if we don't act, the price is guaranteed to be far greater," Twilight said. "Their experiments won't stop, nor will their attempts at sending weapons here, biological or magical that they might be. The possibility of losing a pony is a preferable outcome to the certainty of losing dozens."
"But you can't just ask a pony to risk their life like so," Luna said.
"I can't," agreed Twilight. "That's why I'll be going myself. It's true that I am a valuable target and asset to Equestria, but I am also one of the creatures better equipped for the mission." She swallowed. "If a regular pony were to fail, a new mission would be attempted either way, and eventually I might need to step in. I find it more reasonable to minimise our risks and potential losses from the beginning, and I also consider myself to be better equipped to escape should things get dire, compared to the alternatives."
Luna nodded, and Celestia did too.
Twilight continued, "As an additional safety measure, I won't be travelling to Nightmare Moon's world from Equestria. An alternative route has been found, and the portal between it and Equestria is to stay closed until the success of the mission has been confirmed." She took a deep breath. "If anyone is listening, by the time this recording becomes available publicly, should it, you'll probably already know what the results of my expedition were."
