"Princess--" Twilight said getting a very unlady like snort from Luna.
"LUNA... are you sure you want to do this? It'll be very painful." Twilight corrected herself.
"We don't care at this point just do it Twilight Sparkle." Luna said Twilight nodded then stepped back from her. Twilight's brother, Shining Armor put his shield spell around Princess Luna. He looked at Luna with sympathy in his eyes. Twilight was getting the spell ready when Cadence barged in. Greatly startling Twilight causing her horn to flicker and stop glowing. Cadence looked at Luna with tears in her eyes.
"Auntie please don't do this! This is madness!" Cadence screamed. Cadence had been through the spell for a scan it hurt like HELL. She didn't want anypony else to feel the pain. But to actually get separated from another pony. That had to kill any mortals.
"Twilight Sparkle please cast the spell." Luna said completely ignoring her niece.
"Alright..." Twilight said uncertainly she charged her horn up and got into a fighting stance and closed her eyes allowing her horn to glow red and black. Her aura grew to around Princess Luna's height there was now ribbons flying off her horn. It was still rather hard for a immortal unicorn -- or a demon is what they were frequently called-- to cast. She opened her eyes that were now red and focused on Luna. Cadence ran forward but stopped by her husband. The room was engulfed in black and red aura.
"AHHHHHHHHHHHHH!!!" Luna screamed
