[u][b]⚜Description⚜[/b][/u]
Hassan i-Sabbah (the 3rd) was the next leader to inherit the title and role of being the leader of the religious group that was built upon his previous predecessors. The first Hassan i-Sabbah formed the group using religion to bind together the people for the group, he was not like the first. The second Hassan i-Sabbah continued to kindle the flame of the group with his charm and converted people into joining the group and was far better at reaching different masses than the first, yet he was not like the second. He was different from the other two peaceful leaders, as it was a misconception that the first Hassan i-Sabbah was the creator of the group of assassins. A few stories from within the group blown up to revere the first and second leaders, but in reality, it was him the third who decided to make a statement.

Being the first Hassan i-Sabbah to focus on assassination and make the group's presence be acknowledged and known to people as their peaceful way garnered no respect or acknowledgment from others. He began teaching the group the ways of an assassin, using those techniques as their main political statement. He and his group gained much notoriety from doing so, as Hassan i-Sabbah (the 3rd) was the first to mold and image the group into what they would be called later as the 'Assassins'. His teachings even after his death would continue to spread as a tradition among the group as well, cementing a permanent place for Hassan i-Sabbah (the 3rd) in the group forever. While he may not be the religious leader like the first or like the persuasive second Hassan i-Sabbah who recruited and converted followers but he'll forever be the one who taught them how to make their presence and discontent be known to the public. 

After learning that his victory of the Daeva had changed him completely, he faked his own death and helped the group out by being a simply good member of the group. Rising high in the ranks but never making a buzz about it as he watched the group. Looking at it decay after the switching of leaders, he dragged out the death of the group by carrying a heavy burden of the tasks that they neglected to do. Making sure the important ones were done, and the work did not flow over the top but would never know what would happen. For he died a death he would have been proud of as while none in stood in his path, his bloodied body continued on until it could not do so. Thus, he died like any normal member of the group, its just that there was a delay with his eventual death.

Thus is the way that was paved for sixteen more Hassan i-Sabbah that will never be as good as the original and poor imitations of it, deteriorating as time goes on until they are a sad mess. He is a heroic spirit of untold stories, many unpleasant ones that do not wish to be heard and not wished to be told. It is simply the weight that he carries as the True Servant for the catalyst of 'Assassin' for he gave the word meaning its origins that are bathed in blood and shadows. Standing on a whole another level compared to those 'True Assassins' that the other Hassan i-Sabbah claim to be, he is the only one worthy of the position.  

[u][b]⚜Appearance:⚜[/b][/u]
Hassan i-Sabbah (the 3rd) stands up at a height of 5'10 normally with a muscular yet lithe build which you can see. Having a dark tan skin tone, Hassan i-Sabbah (the 3rd) is one of the most prominent leaders who is second to the first Hassan i-Sabbah. Having such reputation as his time as leader, it has removed the wraith-like appearance that most Hassan i-Sabbah summoned in that Grail War would even have. Giving Hassan i-Sabbah (the 3rd) his own unique appearance that separates him from the others. Letting his figure be exposed through the lack of clothing that he mostly doesn't wear, having his pants be loose fitting black cloth with strands of fabric that fall to the side from remnants of his shirt. Having his black mantle present on him, appearing in a multitude of forms as a black cloak which will completely cover him except for his skull mask. He often doesn't wear his cloak like that and often shifts its form so it no longer covers his entire body, making it appear hood-less, like a flowing scarf, or wrap it around only a part of him.

[u][b]⚜Personality:⚜[/b][/u]
Hassan i-Sabbah (the 3rd) was not as charming or charismatic as the first two leaders and was quite the opposite. Being a silent and serious individual, he was known for getting the job done, cleaning up the mess from other members of the organization and cutting off loose ends when needed. Making Hassan i-Sabbah (the 3rd) one of the most feared leaders, reinforcing his leadership with fear and strict rules which controlled the group in an orderly fashion. He issued a time of fear with his position as Hassan i-Sabbah with his teaching which he spread to his brethren. 

While he may be a quiet individual, he is very observant and has extensive knowledge on the ways that human interact between each other. Knowing how to manipulates humans well during his life and pulling the strings behind the scenes when even not there himself. He is capable of faking emotions himself and creating an outer persona which disguises his true nature.

[u][b]⚜Class Skills⚜[/b][/u]
Presence Concealment (A++):
Assassin's ability to become undetected at this rank is unparalleled to any other True Assassin, in which his presence as a servant or even entity is completely erased along with all traces of his existence as well. The effect will continue as long as Assassin does not attack, but should he perform one, even interception of these attacks through clairvoyance or precognition is incredibly difficult. With the attack working in a similar way to the effects of "Knowledge of Respect and Harmony" as the next angle of attack is unknown. With this rank, it should not be a surprise that the first attack will hit from Assassin.

Even as he's attacking, he can bounce in and out of stealth essentially at the exchange of dropping this skill down to (A+) which still makes him a difficult opponent. He is what truly an assassin meant to be and in essence the true servant for the catalyst of the word Assassin for the ritual.  


[u][b]⚜Personal Skills⚜[/b][/u]
Projectile / Weapon Proficiency - Daggers (A): 
Assassin's proficiency in this skill is apparent to its rank so that even his thrown blades are propelled at a speed and precision that gives even the fastest Servants troubles. Along with his own handling of daggers, being able to dexterously wield them without trouble in either hand or both, they flow smoothly in his hand with much grace in them. Should the daggers are being thrown from stealth they will increase the difficulty to detect or dodge on stop due to his high rank in this skill, making the first attack near unmissable. Skills such as 'Instinct' or 'Protection from Arrows' may give the defending victim a chance to react if Assassin throws his daggers from stealth but still difficult.

Apothecary (B):
Assassin is a trained individual of the art of alchemy. Having a very detailed memory, knowledge and experience in making a variety of poisons, drugs and medication of all sorts. With this much skill, it is also possible for Assassin to create potions and elixirs capable of performing great effects with more obscure effects with some of them capable of being magical in nature. With more magical products having greater effects, they cost more materials to make along with time to craft them but are worth the resources consumed. With this rank, what he can make is only limited by the ingredients available  he has and the time constraints. Allowing a great variety of effects can be reproduced.

The Art of Killing (B): 
A pair of Mystic Eyes of Observation, these mystic eyes are exceptionally good at observation which grants Assassin the skill Clairvoyance at the C-rank which is a part of what he receives from these Mystic Eyes. With Assassins' own experience, it allows him to identify possible causes of death in a target should he observe them, allowing him to determine most suitable poisons, weak points, where and when their guard is the weakest and so on, granting him the skill Instinct at the C-rank as well. The longer the target is observed the more accurate and encompassing the results, should the target be observed for more than 24 hours his information will have 100% accuracy. After 48 hours almost all of the target's weaknesses and a major amount of their information will be available to him. 

[u][b]⚜Noble Phantasm⚜[/b][/u]
Name: Neferipitou - The Living Shadow
Rank: A
Type: Anti-Unit / Support
Effects:
A magical cloak of shadows that was taken from the Daeva of Oppression, Thoth. After the cloak was taken from the Daeva, it was attached to Assassin's body and made a part of himself. With it becoming his Noble Phantasm, it manifests itself like a drape of midnight black cloth that flowed with living darkness of the slain Daeva. Where once it was simply attached to his body has now simply merged together as one and is beyond simply a shroud as it clearly possesses some intelligence. With the shroud granting Assassin power over shadows and darkness that can be used in various clever or gruesome ways due to the nature of now being a part of his body. 

With it now a part of him, he may make it assume whatever shape he thinks is more practical. Normally, it will simply be present on Assassin as a black cloak completely covering him except for the part which skull mask covers. He may shift its form so it no longer covers his entire body, making it appear hood-less, like a flowing scarf, or wrap it around only a part of him it truly is up to him. However, some area around his shoulders and neck will always be partially covered, since that was where Assassin originally grafted the shroud to his skin. It changed him into something not entirely human, infusing his body with whatever was in the Daeva that changed him both from the inside and outside. Living up to twice his age and becoming quite hardy that his wounds healed faster, while not notable it was something which was beyond human abilities he took his time and continued to guide the Hassan i-Sabbah even after he faked his own death. 

But that is not the true nature of the shroud's power, which really instead allows Assassin to transverse shadows within a limited distance. As long as he is touching or within a shadow, he may sink into it in order to emerge from another shadow. This includes his own shadow. However, since this dislocation in space using shadows as a medium approaches the realm of True Magic, the maximum distance he may cover is about 200 meters in one dive. The prana cost will be higher the longer the distance he wishes to transverse, and increased by repeated usages. Due to the properties of Neferipitou, it's also possible to store up to an additional 50 lbs of items in there before interfering with his shadow traversing abilities. Capable of storing up to 100 lbs if he wishes to completely forsake traveling through shadows, making his dominion is the shadowers even deeper.

One of the shroud's ability is to manipulate its form, capable of being controlled by Assassin to solidify itself it also has its own form of sentience. Able to be used in a multitude of ways such to unsuspecting attack in whatever form his mantle is in, the cloak itself defends Assassin from attacks that it can perceive and react to, along with coordinating with the movements of its wielder. Capable of moving flat on the ground literally as a shadow or leaping off the ground as a ribbon of darkness. However, when using this ability, it can only move to a maximum of 55 meters and seals his ability to travel through shadows unless it is within 5 meters of him but he can treat his shadow as another eye which he can spy with.

I plan to make a Assassin which isn't blown away by the three knights classes so why not start with the one who made the word 'Assassin' a thing? 

(I planned to make Artoria a caster and summon Camelot with Caliburn after modifying her backstory so that the sword didn't break but I'd probably fail to stay in character. She'd have Caliburn as her sword and noble phantasm, Camelot as her 2nd noble phantasm and Knights of the Round Table as her 3rd Noble Phantasm! But that'd remain in the drawing boards for now.)
