The mare kept her eyes on the notebook when she was addressed, her finishing the sentence she was rereading while simultaneously turning her ears to listen to the questions of the two guards. Once finished she looked up and gave a small smile, the mare then tapping a hoof lightly onto the ground as she closed her notebook and tucked it up against her body.
"Hold on..." she said, continuing to tap as she scrunched up her face a bit in focus, the pony visibly trying to work something out in her head, "... One sec... I know this... Um... Bonjour! Comment... e-est la météo? Où pa... peh... peut-on trouver... um... une salle de... bains?" She giggled a little before taking ok a slight shade of embarrassment.
"Sorry. I'm trying to improve my understanding of some more languages to help with my job. Juuri nyt olen vain tietää muutamia." Another smile, followed by a blink and ending with a another look of embarrassment. "Er... Anyway, about your questions. Princess Celestia has always been trying to make plans for bringing over the artifacts left at the old castle, but something usually tends to divert her attention. Right now though, Instructor Gleam hasn't been giving her a chance to get distracted as he thinks he's found a good use for the artifact and has been bringing it up with the Princess a lot lately. He wants to study it, and she trusts him, so that on top of her desire to bring these things here already seems a good enough reason to bring it home." The mare took a moment to brush a strand of her mane from her face before glancing back at the door leading to the Princess' chambers
"Or, well, that's how it was a couple weeks ago. Originally this wasn't going to be as big of a deal, but since then we've learned that Gleam might not be the only pony who has been looking into this... Gleam actually does have a point about the magic surrounding the vault at the old castle. It is indeed becoming increasingly outdated as the centuries roll by, the power behind the spells and enchantments also losing some of their energy as well and simply weakening with age, so... if other ponies are looking into this star thing and really did want to get into the old vault, we could have a problem... Add all of this together and we get you two here gearing up to solve this.
"As for why only just the amulet gets to be escorted to the city? Well, if we remove the current item of interest from the old vault and put it somewhere where we're sure nopony can ever get to it without us knowing, the Princess hopes that will remove some of the interest in the old vault for now. You know, once news 'leaks' that its safe and sound. Most of what's in there is really really difficult to find any information on, so chances are the possible ponies looking to pilfer for profit won't know about any of the other nasty knick knacks in there, and why risk your life on a gamble, right? If the ponies were smart enough to learn about the star whatchamathing then they are probably smart enough to avoid one of the most dangerous places in the country once said object is no longer within reach. At least, thats what were hoping. Then there's how taking more than one of what's in there would, as the Princess said, draw too much attention. Should a unicorn anywhere near there do a sweep for magical energies you two would light up like a beacon. Best to keep this low key. Especially when you two are carrying a certain key."
Turning her attention to the stallion of the pair, the mare only shrugged slightly.
"Eh. I already know everything they're going to talk about, so she probably just wanted to discuss a few things other than work. Or maybe more work. I dunno. Either way, if there's anything I need to be made aware of for the Princess' convenience I be filled in when they're done. My name is Pen, by the way. Pen Sketch. Some ponies call me Penny, and I'm Princess Celestia's personal assistant. Number one if you want to get playful about it. If I'm right about you two becoming regulars then I'd like to make sure we at least know each others a bit. Bastion. Blossom. Or do you two prefer to be addressed as Aurora Noctem when together?"
