Surviving Equestria's Queen

Starlight brought up the report of the guard interrogations and slammed it down on Twilight's desk. “Alright, every guard has been interrogated and found innocent. Can we move past this crazy theory of yours?”

Twilight frowned, bringing a hoof to her chin. “Hmmm, it must have been a crazy scientist, then.”

“I'll take what I can get.” Starlight teleported the report into the volcano. “Now, since we’ve completely failed to do any containment procedures, the zombie horde has grown considerably and is now trying to get into Canterlot. The guard has managed to make a defensive line to push them back, but they'll tire eventually and will need to fall back to a retreat position. What do we do?”

“Have the ponies from the surrounding villages been evacuated into the city?”

“Yes – those that managed to survive the horde, at least. We've made an improvised camp near the front gate for them to stay.”

“Have they been checked for bites?”

“Yes. All of them.”

“Did you use dogs?”

Starlight blinked. “Use… dogs?”

“Yes, to sniff out the infection.”

“That’s… what? How would that even work? How would we even get that many dogs? They're as rare as dragons.”

“I'll take that as a no…” Twilight said grimly as she stood up, and started to walk towards the window.

Starlight followed her with her eyes. “What are you doing?”

“I can't risk the infection spreading within the city.” Twilight said as she looked out the window overseeing Canterlot and lit her horn with her purple aura.

“Wait! I can assure you we've been very thorough in our searches. There's no way that-” A blinding flash of magic forced Starlight to stop, closing her eyes and looking away. Then she felt the entire castle shake as if an earthquake had hit, and then the blast of sound and heat came last.

She quickly ran over to the window and witnessed the large mushroom cloud coming from the crater that was once the front gates to Canterlot.

“It had to be done,” Twilight said somberly. “We can't risk a hidden bite dooming us all.”

“Oh, but blowing up our first line of defense is fine?! That's where our troops were meant to retreat to! What will they do now?!”

“Their sacrifice will be remembered, they're heroes.”

“You thought they caused this just a few hours ago.” Starlight sighed. “Wait, can you nuke the zombies?"

Twilight chuckled "Oh, Starlight, everyone knows nukes only make zombies more powerful. We don't want glowing ones, do we?"

Starlight blinked. “What's a glowing one?”

“I'll explain when we've more time. For now, we need to set up a barricade along the non-infected areas to keep the zombies from reaching further into the city.”

Starlight sighed. “It won't compare to actual walls made of structurally stable stone, but I guess it's the best we got. I'll give the orders.”
