Astolfo

Astolfo comes from the world of FATE.

In fate, mages make up a secret society of magical practitioners who often fight with eachother over power and struggle to cooperate. Most mages are fundamentally cruel to be better at the pursuit of magic and backstabbing eachother, with a few exceptions.

In FATE, every so often, a grail war is declared. A grail war a great survival game between 7 mages who summon heroic spirits, the powerful ghosts of legendary and historical figures given life by the grail, to fight for them. The grail itself is an incredibly powerful sapient magical artifact that is one of the only sources of true magick left in the world. It will grant 1 wish to the victorious mage and their servant. The mages and their servants then proceed to seek out and murder eachother until there is only one pair standing.

There are 7 heroic spirit classes: Saber, lancer, rider, caster, berserker, archer, and assassin. There can only be one of each type in the grail war, paired with a partner mage. There is occasionally the secret ruler class but this class seldom appears.

Each mage gets 3 command seals, magical commands that force a servant to do whatever they say. They appear on the mages body as tattoos gear vanish on use.

Each heroic spirit has noble phantasms. Special powers (allegedly) tied to their legend.

Astolfo has several noble phantasms: La Black Luna: A hunting horn that strikes fear into the hearts of all who hear its sound, prompting instinctive escape. Those within its range will be struck with the shock of an explosive sound. In the case where the damage is the same or higher than the target's HP, they will be turned to dust and scattered around. Does not affect Heroic Spirits with Magic Resistance, but normal mages are not immune to its influence.

Casseur de Logistille: Inherited from a certain witch, it is a book with the means to shatter any and all magic recorded within it. It does not cancel a Reality Marble or a greater magecraft exceedingly close to Reality Marbles to such an extent, but evoking its true name and reading its content makes it a possibility...

Trap of Argalia: Lance of the knight, Argilia. Has a golden tip. Killing ability is low although a wound is inflicted to the leg of the spiritual body. To come back from falling, a LUCK check is necessary. In the case of a failure the bad status "falling" continues to linger. However because LUCK re-adjusts itself upwards, it's not hard to succeed.

Hippogriff: A Phantasmal Beast that's essentially an "impossible" existence. Allthough its rank is inferior to a Griffon from the Age of Gods, its charging pulverization attack is equal to an A rank physical attack. For only a moment, it is able to place itself in an inter-dimensional rift. Therefore, it is able to phase through every single attack.

Astolfo has magic resistance.

Astolfo is from the Carolingan cycle/Matter of France, a body of very early legendary french literature depicting the history of France where he's shown as one of the 12 heroes of Charlamagne. In this, he is a prince, son of Otto, King of England(historians think this might be Offa, Duke of Mercia who was a contemporary to Charlamagne.) He also appeared in Chanson de geste(song of heroic deeds) and The four sons of Aymon. However most of our modern understanding, and what shapes astolfo as a heroic servant, comes from later epic poems and media like La Prise de Pampelune, Morgante, Orlando Innamorato, and Orlando Furioso(most important)

Plot of Orlando Furioso as it involves Astolfo: When first introduced, Duke Astolfo is trapped in the form of a myrtle tree by means of the evil sorceress Alcina's magic. When Ruggiero attempts to tether his hippogriff to the unlucky man, Astolfo protests, lamenting his fate. Although the two converse at length, Ruggiero does not heed the duke's advice to avoid Alcina and he soon becomes bewitched as well. Both are, however, rescued and returned to normal by Melissa, the good sorceress. Astolfo possesses various magical equipment which he employs throughout his adventures. His magical golden spear can knock opponents off their horses with the slightest touch, and his magic book contains spells capable of breaking any enchantment and was very easy to consult thanks to its alphabetical index. He also owns a magic horn, whose blast is so loud that it causes all enemies to flee in terror and rides upon a horse named Rabicano. This magical horse is made of hurricane and flame, feeds on air and it treads so lightly that it doesn't leave footprints in the sand, and when it runs at full speed it can run faster than an arrow. Astolfo defeated the giant Caligorante, who threw a net stolen from the temple (one that Hephaestus had used to capture Aphrodite and Ares during their adultery), then trapped and devoured all the travelers who passed near him. The hero managed to defeat him thanks to the noise of his magic horn that scared Caligorante, who ended up falling into his own net. After defeating him Astolfo parades the giant from city to city, forcing him to act as his beast of burden. He also defeats Orillo, a thief who could not be killed because he was enchanted to regenerate from any injuries he received. Even amputated limbs would be reattached. Astolfo defeated him after looking up his name in the index of his spell book, thus discovering that to defeat him he had to remove all the hair from his head, knowing this Astolfo proceeds to cut off Orillo's head and then escape on his horse while the thief's headless body chases him, after getting far enough away Astolfo sits with the thief's head on his knees and proceeds to cut his hair with his sword, thus killing Orillo. Astolfo loans his golden lance and Rabicano to Bradamante for a short time while he rides the hippogriff in search of Orlando's lost wits. Astolfo travels to Ethiopia where he met Senapo (Prester John), the emperor of that land. In a situation similar to the story of Phineus from Greek mythology, Senapo is blind and plagued by harpies who attack him whenever he tries to eat a meal, spilling the glasses and befouling the food. Astolfo blows his horn and chases the harpies through the entrance to Hell, and seals them inside. He flies the hippogriff to the summit of the mountain of Terrestrial Paradise, where he meets Saint John the Apostle, who explains how he could return Orlando to his senses. He flies in Elijah's flaming chariot to the Moon, where all things lost upon the Earth end up, and locates Orlando's wits in a bottle. He returns to Earth and gains Senapo's aid in the defense of Paris from the Saracen invaders. (From wikipedia)
