Appearance

Aurelius is often seen as rather handsome, with crimson red hair usually brought up in a pony tail, and red eyes, and fair skin covers his body. He stands a bit above the average in height, and his body is muscled from hard training, though he isn't as built as a body builder or thin as a swimmer or runner. But even so,he is often called "feminine" do to his rather fair, if not downright beautiful face and thick eyelashes, which annoys him to no end. 

He also has several scars across his body, from battles across timelines whenever he has to step in to prevent total disaster for said timeline (unless it is meant to happen)

His hair shorter

Personality

"He comes often off as a calm and charismatic man, often speaking in such a way that you would believe he has the whole world in the palm of his hand, or knows a big secret that you don't. Hell, some would say his carefree and only lives for a good fight, though I know better, he lives for the Grail just as much as the next Ruler."

"Friendly and polite, yet his eyes reveals that he is also cold and ruthless to those that he deems as foes,a haunted yet serene look shining in his eyes".

Aurelius is all in all, a calm, mature and somewhat silent individual, often seen as stoic and serious in most situations, taking his duties and tasks extremely seriously. He is more of an observer, preferring to take a step back and analyse a situation before taking action.

He is most often seen as cold and distant, practical and ruthless in combat to get the best results as quickly as possible. But even so, he is kind and gentle when needed, most often towards children. 

He respects and even admires many of the mighty Heroes that he has encountered (either from observation or direct interaction) through his missions across the Multiverse, and strives to be like them. 

But even so, he has a few old habits from his past life as a mortal, such as his pragmatism that he got from his former mentor, and while he truly wishes for the good of all people in the world, also accepts the darker and harsher realities of life, and both envies and pities the naivety of the hopeful.

Armor

Origins and material unknown, though many speculate that it was created with an intent or inspiration that the Hero has recorded and observed through his time within the Grail and the heart of the Throne of Heroes. Being magically resistance to some degree, and durable yet agile for fast and almoost acrobatic strikes.

Modern clothes/Outfits

And while observing Heroes from different timelines, Aurelius will usually just manifest with clothes appropriate for that timeline

Weapons

  A sword he named simply "Clara"

"The sword that penetrates the core of the earth, quenched in it's fire so that it could burn with the holy flames to guide the lost in the dark.... or so he claims"

"An unnamed spear, yet dangerous, wielded like it's very presence should be respected... and feared, The Ruler seems to favor this weapon above anything else"

A Dragonslayer spear, as it's origins suggests it has been used to kill off the mighty beasts of the skies, thus makes it highly effective against opponents with dragon origins or connections

The Catalyst to summon him

A piece of the red mane from his helmet, or one of the red gems from his armor.

Powers/Abilites/Noble Phantasm

"Brightstar"

When charged with enough Mana, the blade/s take on a bright glow, and when released, unleash a lethal and devistating blow

Mana reserves

Has the ability to build up and reserve his mana for later use.

His natural abilites are highly enhanced, such as streanght, sight, hearing, reflexes and speed etc.

Next to photographic memory

Reality Entanglement

he ability to fuse with the world he is in, almost like Presence Concealment where the person hides their being from being noticed by other Heroic Spirits, only that he hides his true self from the very reality itself. It makes him hard to make out form a crowd, so unless he deactivates the Skill. His presence won't trigger any otherworldly or magical alarms.

Shield

As simple as it sounds, Aurelius can manifest a golden barrier/shield made from pure Mana to protect himself, however the strength of the barrier depends on how much Mana he pours into the barrier, and how powerful the attack against it is.

Clairvoyance

Clairvoyance is the claimed ability to gain information about an object, person, location, or physical event through extrasensory perception, however while summoned as a Servant, his Clairvoyance is highly reduced and limited, and works more like a Master's sight as he can somewhat make out another Servant's stats and maybe in some circumstances, see what theur Noble Phantasm could be, or a hint of it.

Clairvoyance of Stellaris

Is a devistating attack, where he charges mana, which takes the form of sunlight taking the form of lightning, and can either coat his spear/swords with it, making them lethal, or throw the lightning, which can then multiply into several spears after the throw.

Other

Has his own 'realm' within the core of the Grail, usually a vast space with a reflecting floor and a sunset in the endless distance, with mirrors floating around that shows the heroes of the different eras like a film, Ambrus' way of archiving and recording the heroes and legends.

But he usually makes the "Pocket Realm" manifest as a vast landscape, with a giant purple flower field.

His wish from the Grail, is to be given life again, so he can have a chance to earn his place in the Throne of Heroes like the legends he has observed.

Backstory

His origins are unknown to the mages and other Servants, along with his purpose in life, only that he is able to be summoned as a Servant, and is a great fighter. However what most don't know, is that he is the manifistation of humankinds accendance, the Epitome of Man at their highest and most glorious time from across all timelines and multivurses. But his presence is a mere idea, a concept of how glorious humans can become, manifested by the Grail as an aid to record and inprint the legends and stories of the great heroes throughout history, and archive them within the Throne of Heroes.

Aurelius was once a normal human though, born into the world of Magi, he was however specifically born to be used for experimentation by a rouge magus that the clockwork and Church was hunting down. For years he was used to try and perfect the magus' abilities through experiments. However one day, the infamous Magus Killer was hired to track down and kill the rouge.

After after doing so, he took the boy with him, naming him and started to train him as his pupil of sorts. Years later he followed his mentor wherever he went, going on contracts and other missions with Kiritsugu. Even as the Killer was selected for the Third Holy Grail War by the Einzberns, and was there when he married Irisviel, helping them when little Illyaviel was born, he met the legendary King of Knights. Finding a decent friendship with her as they fought in the war. However he met his death at the end of the war by the hands of Gilgamesh the King of Heroes, known as Archer during the war. But instead of death he woke up in a grassy field for as far as the eye could see, only to know his new purpose like it was printed into his mind. And thus started the life of the Golden Lion, the keeper of the Grail and Throne of Heroes.

So though this he doesn't have his own legend or mark in history, but a general representation of all the legendary heroes and villains, along with humans victories and defeats. He has seen things that he knows isn't his own accomplishments, yet he feels pride in what they have done. His only wish is to serve as the heroes of old did, and to perhaps leave his own mark in some way, which some of those that knows his story believes is the naive part of his being that hopes.
