In response the CCU made a rattling sound of clattering metals against each other, and a peice of armor on its arm falls off*

*Nightmare Moon jumps aside as the armour comes crashing down. She then leaps up onto the CCU, and begins dissolving a hole into it’s armour with magic, trying to burrow inside it and confront whatever’s in there.*

Greetings. First of all, i wanted to -ahem- congratulate for your foals. Three of them, that's right? It's quite the family. I wanted to ask a thing: in this "everlasting night", will my experiments be tolerated? I do things that people don't fancy and can't be done in the sunlight, metaphorically speaking.

Unlike Our thick-headed sister, or wonderful kind-hearted Luna, We understand that scientific advancements that benefit everypony sometimes come at a cost, though We prefer that ‘undesirable elements’ 'volunteer’ to pay said cost.

I just wanna hug their necks till they drop...

And what will you give Us if We allow you to kill one of Our guards?

*All the guards within earshot of the conversation flee in terror.*

Healing powder , a bitter drink that makes a hornless pony magical for a short while , a dust that can disarm a unicorn of its magic for a short while , and finally poison darts.

We have spells that can preform all those tasks. But perhaps… What sort of poison do you tip your darts with?

ICH TU DER WEH

Ich bin der überbringer des terrors.

Galaxiour; My child! I came as soon as I could!

Father, Equestria is under attack!

An alien empire sent an ambassador to Us, attempting to browbeat Us into signing a treaty turning the planet over to them. When We refused, their ambassador tried to assassinate Us and their forces invaded!

May I have one of your guards?

It depends. What do you want with them?

(A silent, alicorn-shaped form enters the room. It says nothing. It looks at nopony, or perhaps at everypony; it is difficult to tell, as the figure shines brightly and has no discernible features. After a moment, it walks toward Nightmare Moon, fading away and disappearing halfway.)

*Nightmare Moon glances at the figure for a moment, but is too intent on the CCU to investigate further or try and follow it.*

The CCU, while seemingly off, gets up very slowly. A deep, raspy breathing is heard through its speakers.*

*Nightmare Moon has approached close enough to almost touch it. She stops and looks up at it.*

You dare threaten Our children!? This is intolerable! We shall not rest until your kind is extinct, and the name and history of your race is forgotten!

*smiles* Mara is perfect... *then the CCU thing happens, behind the barrier with the foals, can't really do much himself, ready to veil nightmare though if something does happen*

*Nightmare Moon moves closer to the CCU. Her horn glows, and a rift opens near Arcel and the foals.*

Arcel, take the foals to safety! We can handle this!
