Luna frowned, as well as Celestia. Tia sighed. "We were ready for times like this." She said. "Come." She said leading them to a quite odd but interesting room.
"This is a special room in case something like this happens. It will keep us safe from both the infection and the 'zombies' if Canterlot were to fall." Tia explained. "It has capacity to have all of us and a big group of scientist or years and we will also be able to carry on with everything in here."
"Yes, but we will use that in case this goes worse than we expected." Tia then said "For now it just wil be out HQ for this thing."
Tia nodded. "Alright." She went to get ready some stuff. Luna and Darky went to a sort of living room in there, sat in the couches and snuggled each other to calm down.
Luna and Darky were still snuggling each other, looking now quite happy as they did it. Tia came back. "Everypony, you know what to do, so get to work." Tia said to them, then they went to work.
"Me too."-CM snuggled Star back. Outside, at Ponyville, zombies are raising, there was only a few survivors left.They're coming to Ponyville... Slowly...
Celestia send a group of guards to search for any survivors in Ponyville,hoping they would bring them to Canterlot safe, or at least all they could. The Ponyville train station was quite heavily so more missions could be held in there.
"S-smallpox?" Luna was also astonished by that. "Kill a virus with another virus?" She said. "Like fighting fire with fire?" Darky said. "I... I don't like this, aren't there any other options?" he said.
"This one seems less dangerous than that Necroa virus.Besides, we already have treatments for Smallpox.I think we should..." Wright got interrupted by a really loud sound... It was a zombie horde!
