As Nightmare yelled she awoke the group of foals and the terror before made them all scream loud.For their fellow captive had his hooves nailed down to the stone bed he was one with chisels,his barrel opened,all of his organs on a metal plate,and a bloodied Nightmare Moon standing by his body with a glare mixed with anger and insanity.

"Silence!" She bellowed silencing all but one Earth Pony filly. "Hmm what do we have here?A volunteer.Well come on up don't linger"

As the filly continued to wail Nightmare shut her up and pulled her over with her magic staring her in the eye

"Well let's have some fun then.Shall we?"

Nightmare took the filly to a rock wall that had chains and shackles on it.She put the filly on the wall and closed the shackles around her hooves made sure they were as tight as possible and brought over the collection of the, bloody, tools.

"Hmm what should we use on you little one?" Nightmare whispered into the filly's ear causing her to squirm even more in her shackles."Oh yes this will be interesting."

Chuckling Nightmare picked up an awl and picked up the bloodied hammer and aimed it right over the filly's top left hoof and hammered the awl into her ergot and hammered it into it.The filly howled in pain at her hoof virtually being cut off.Nightmare grinned at the filly's pain,and for a moment felt pleasure in what she was doing.And just now Nightmare amidst her feelings of anger pleasure and giddiness did she remembered about the other foals, she looked over and saw them in a similar position as before cowering and sniveling in the corner of the cave not one brave enough to run or do anything else.

"Now let's see what should I do next?" Said Nightmare, again examining the collection of tools."Aha!This will nicely" Nightmare said grinning while looking at a very sharp and deadly looking exotic dagger.

Nightmare picked up the dagger and held it to the filly's flank and slowly engraved her cutie mark of the Moon and it's shadow into her skin.The filly whimpered in pain as the blade sliced her flesh and fur burning as Nightmare went.Eventually, Nightmare came to a stop,put the dagger out and picked up a much more terrifying scalpel than the one she used before,and began to cut along her right cannon to her elbow then to her flank and to her tail leaving a very large gash.Next Nightmare began to slowly peel back the skin across her barrel until most of her muscles were in sight.Then,she slowly started to cut across her whole barrel making a large five-pointed star.Then, Nightmare started to cut each non-major vein she could find.By now Nightmare had noticed that the filly had noticed that the filly had passed out and her coat was losing it's color.Nightmare revived the filly and continued on her procedure.Then she suddenly stopped, picked up an axe and began to fervently hack at the organs slicing each one into bloody ribbons.While looking quite fierce Nightmare was actually planning where to hit and the landing of each and every slash.

With most of her organs destroyed the filly was close to dying,but Nightmare wouldn't have it.She used the revive spell again on the filly but it had a lesser effect.As the filly was beginning to breath her last,final breaths Nightmare ripped her tiny intestines out and strangled her to death with her own intestines.The filly died staring into the eyes of a cold, heartless monster.
