Frozen Dream

Shining Armour sighed as he read through the reports, once again the royal guard failed to protect the ponies they swore to protect.

The captain glared at the papers that was laid out in front of him, the main focus point was the assassination of the Star Shine, the famous movie director.

"Star Shine found dead in a recording room, found with a broken nose, bruise muzzle and slash mark across her neck, possibly from a katana, a message written in her blood that read 'Dreams Dont come true' was found frozen" Shining read under his breath, his skimmed through the rest of it that involved the relationship and occupation of the mare and focused on the possible suspects.

The suspects were of course ponies that had a celebrity status, ranging from the photographer Photo Finish to the pop pony sensation Sapphire Shores, they listed off the reasons why they would kill the movie director, the typical reasons like afraid of being out shined, jealousy, a heat brake, and one of them was that she tried to ruin the image of a pony.

Shining Armour knew that these ponies could not have killed Star Shine, hired somepony to kill her for them yes, but do It themselves not a chance, he sighed, though something from Sapphire Shores section caught his interest, it stated that she was seen with a rather familiar face.

His eyes went to another report, this one giving crucial evidence to who might have been the killer.

One of them was what happened to the bodyguards that were supposed to protect the movie director, when asked all they answered were 'We saw something blue, then everything turned black' the others gave the same answer, though one stated that he was able to catch a glimpse of the pony, before getting knocked out, according to him the killer was unicorn.

Unfortunately the pony was able to take out any surveillance cameras that were inside the building, fortunately he forgot to take out the one on the outside, from the tape they were able to find out that he was a stallion, and indeed a unicorn, they weren't able to identify his cutie mark, nor were they able to catch his face.

Leaving the message at the body of the mare was a mistake, as the guards were able to use the magical residue left by the spell to figure out the magical signature of the unicorn, obviously ice.

With all the information Shining Armour was able to figure out who was the one responsible for her death, he sighed and rubbed his temple with his hooves "I thought that being prince would lighten the workload, I was so very wrong" he muttered, his horn glowed and a rather thick folder from his cabinet glowed the same and levitated towards his desk, he moved the reports out of the way and dropped the folder on his desk.

Using his magic he flipped it open, the first revealed a mugshot of a Dark Blue unicorn, he had a spiky mane of the same colour that was a few shades lighter, his eyes were icy blue, on his flank was a snowflake that was sliced right in the middle, his bio-data stated that his full name is Diamond Dust, he weights around 45Kg, approximately at 3 feet 1, and possible at the age of 21, the rest stated his previous locations as well as his former subordinates.

Below the bio-data is his weapon which was a one sided katana that was two feet long hidden in a blue scabbard that can be called upon by the pony, this is used to avoid the weapon from being stolen, though If it is out of it's owners magical range, or is blocked by an enchantment it would be lost unless retrieved.

His magical signature was ice, and obviously he is very skilled with it, his main strategy is to distract his opponents and bombard them with ice spikes to either incapacitate them or kill them, he also uses the ice to increase the length of his sword and uses a unique spell that'll freeze the pony touched.

Then below was the pièce de résistance, unlike most unicorns who would rely solely on their magic and weapons, Diamond Dust is different, it stated he's speed in nearly unreal for a unicorn, apparently fast enough to disappear to civilians eyes and appear as a blur to trained ones.

Fortunately he was not perfect, his ice attack is less effective if attacked in a group as they can render the ice bombard useless if they can detect it and destroy them before they pose a threat, his speed can used against him to knock him off balance, and If fought long enough, his movements can be memorised, reports show that he is also greedy, a trait the royals guards have been trying to exploit, with little success.

They rest of the folder was filled with reports of the work he had taken, most of them being assassination while some are escorts that landed some of the guard into the infirmary, most of his assassinations are a success, oddly though, any attempts on the palace ends in failure, guards report that they would catch Diamond Dust escaping wounded.

Reading the various reports, he found out the last known pony to interact with Diamond Dust was Sapphire Shores, at a local pub, it claimed that they were discussing something in a small secluded corner, this was only a few days before the assassination.

Shining sighed and closed the folder, levitating a highlighter he circled the picture of Sapphire Shores, though rather cruel to classify a pony as a prime suspect because of a chance interaction, no other leads would come through, unless the other suspects suddenly became experts in ice magic, which is very unlikely.

Using his magic his opened the door and called for a messenger, giving the pegasus a warrant and a scroll that informed the guards who the prime suspect is, he ordered the messenger to send it to the guards patrolling Canterlot, with a salute the pegasus zoomed out the office to perform It's task.
