Anyway, this is just a hypothetical side story I came up with because someone wanted to know what would happen after the death of Luna. Celestia, being the merciful fool she is, was trying to 'uncondition' Pinkie, who escaped.
Anyway, third part.
Rarity kept her vigil. The cyan pegasus slept under her watch. She doubted that the guardspony even knew she was there. Rarity watched her like a hawk. Ever since the incident, she ha-
She knew she was there. What had told her, she couldn't say, but she knew she was there. Rarity was already moving, already yelling for backup. But she knew it was futile. Before the Eversor would have gotten this close, the guards would be long dead.
Dash woke at the sound, and tried to get up. But she was still groggy.
The singsong voice came.
"Heya fillies! Pinkie is here for you!"
Dash was clear thinking now, and the terror in her face was evident. The hoofsteps resounded through the building. Rarity drew a pair of swords and tossed one to Dash. In a daze still, Dash caught it expertly and prepared to fight.
The attack came without warning. Two knives were tossed through the air. Dash saw her doom approaching and tried to pray, but before she could even let a 'Please, Celestia, forgive me, and remember I am just a pony', Rarity's sword flashed and knocked them from the air.
"I'm an assassin too, traitor. You'll not get us so easily," called Rarity.
"Oh, that's good! Mica was only a bit of fun. You'll be a whole bundle!" came the reply. Rarity and Dash lifted their swords into the guard position.
Pinkie came hurtling from above. Rarity lifted her sword up just in time and parried the attack, sending her to the ground. But Pinkie was quickly up again and attacking. Almost absent-mindedly, she sent two daggers flying Dash's way, just as her sword clashed with Rarity's. Dash tried to dodge them, but she missed one and it grazed her left foreleg. She winced, but moved to join Rarity in the fight.
Rarity moved in a classic example of the art of the Culexus temple. Moving faster than could be thought possible, she swung her sword in a devastating series of attacks.
All to no avail. Pinkie blocked them as deftly as if from an infant, and moved into her attacks. Rarity was just as quick as she was, and blocked them all.
All except one. She was grazed on the leg and fell down. She tried to lift herself up, but she couldn't move. She looked helplessly on as Pinkie grinned in childlike joy. Dash moved to try and protect her rapist from her enemy. But Pinkie had already killed her, disemboweling her so quickly she hadn't noticed.
Dash collapsed over her entrails, and the light of life left her eyes. Rarity watched helplessly as Pinkie left the room. She tried to speak, but even her mouth refused to obey her. She tried to cry, to weep, but her eyes were no longer hers.
She tried to breath.
