Cipactli: Kinda reminds me of that Otesanek sheet from a while back, despite the completely different mythos
William the Conqueror: Not sure why he's a Lancer specifically over any other Class (I mean he's usually depicted with a sword)? Is it also because of his banner? Otherwise, pretty good
Baron Munchausen: Always a fun Servant, and this'd be the first time I've seen him stated as Archer (sorta), with how he combines his two Classes through Riding projectiles genius. Only real issue is you might wanna split his Personality paragraph up a bit for readability
Anyway:
Caster of Games

(By
Shokushu Ura)
"It's easier just to think of everything as a game. Spares you the shock of what that game has in store for you..."
True Name: Alfonso X of Castille
Alt. Classes: Ruler, Rider, Saber
Source: History
Region: Iberian Peninsula
Catalyst: His equestrian seal made into a gaming chip. His likelihood of summoning exponentially increases if the six other Servants have been summoned before him
Armament: Board games and books, though carries a sword side-arm in case things get physical
Character: Alfonso X the Wise was a Medieval Castilian King, most celebrated for the ground-breaking literary and scientific accomplishments of his court, primarily in the fields of astronomy, translation, music, and lawmaking. His military career however was less fortunate, starting out promising with his conquest of the Algarve, but tarnished by subsequent civil wars with nobles and in the end a rebellion by his own son, the later Sancho IV.
He had a particularly strong interest in both astrology and board games, believing the two were closely intertwined. This combined with his reign’s rise and fall and varying fortunes in war has altered his psyche, perhaps as a coping mechanism, to view all human history as itself a game. A game played by the stars, refereed by God, and with humanity as the pieces. His perspective may seem Boethian, though caster still believes skill factors into things, even if that skill too is predetermined.
Caster judges people’s worth by their intellect, be that in knowledge, skill, or both, and if that’s the case then your faith or nation won’t matter to him. After all, his fellow Castilian Catholics have given him enough grief on their own. But even skill and knowledge aside, he cannot help but be irritated by people who believe in free will, who insist they make their own fate, as Caster views his entire life as proof otherwise.
Naturally he is excited for the Grail War, seeing it as a gathering of the ultimate pieces in humanity’s game, and in general confirming his belief in history as one great game. As much as Caster’s belief in himself as a king was shattered throughout his life (having your own son rebel against you will do that), he does not see his knowledge of fate and games as having diminished one bit… even if it may need some updating.
Attribute: Star
Alignment: Lawful Gaming, originally Lawful Good before life hit him hard
Likes: Astronomical chess, chivalry, the number 7, having other people do the work for him
Dislikes: ‘Unchivalrous’ Cheaters, rebels, free will proponents, his latter reign
Relationships:
- Estella: “Hearts as pieces, or lives as pieces? Luck and skill decide everything either way…”
- Zaroff: “I’ve hunted the Most dangerous game myself. It’s called War.”
- ‘The Boss’: “I can see the Book of Games will need a massive expansion. But kindly let me pass, will you? I believe I’m the one who initiates the games around here.”
- Christina: “I don’t blame you for getting out of ruling when you could, perhaps I had too much pride or too much at stake to do that.”
- Kafka: “Humans are but pieces of the stars, it'd be a privilege if our species really were the cause of all its ills.”
- Chatelet: “First Law? Oh, of ‘Thermodynamics’, I assumed you meant legality.”
- Berlioz: “…Seems music may have gotten a bit, well, out of hand since my time.”
Master: One who views the War as a Game like Extra-Shinji, or Astromancers like an Animusphere or Wodime.
Natural Enemy: Sancho IV. The Assassin Class as matter of principle, being the least likely to play fair
Wish: One last success, roll of the dice, so the end of his legend is no longer in failure.

Class Skills
Item Construction
Skill to manufacture items.
- Rank C: While Caster does have the ability to create items on his own, such as lyrics and lawbooks, most of the wondrous artefacts associated with him were created or translated by others for him. Not that he deserves no credit, having been their patron who enabled them to do so in the first place. So while this Rank is relatively low, through his Personal Skills he can grant others Item Construction of an equivalent Rank.
Territory Creation
Establishment of a territory suited to a magus.
- Rank A: Creation of a ‘Royal Court’, consisting of multiple interconnected Workshops for himself and those he sponsors, is possible. Workshops can take the form of Observatories, Concert Halls, Libraries, and Caster’s favourite, Gaming Parlours. Caster prefers to have seven Workshops going at once, not because he couldn’t create more, but due to his preference for a Lucky Seven.
Personal Skills
All Kinds of Patronages
Ability to sponsor and grow the talents of a wide range of creatives.
- Rank B: Able to increase the skills of translators, linguists, lawyers, writers, musicians, astronomers, historians, painters, soldiers, farmers, and game developers. Patronage of mages however is covered by Technique Elucidation.
Burnout and Fadeaway
Almost an inversion of Child of the Sun. Signifies one who had prodigious success in the beginning of their legend but was met with increasingly failures later in life.
- Rank A-E: Caster had great military success early in his reign, but subsequent civil wars, attempts to become Holy Roman Emperor, and finally a rebellion led by his own son saw that early greatness extinguished. Caster’s stats will start at their highest but will gradually diminish every four days in your standard 16-day Grail War, or every seven days in the Moon Cell. This makes him the opposite case to your usual Caster, who usually get stronger with more time to prepare.
Magecraft
Knowledge of the magic of the Age of Man.
- Rank B: Caster and his court were particularly renowned for Astromancy, as well as luck-based magic in general and some specialty in Bardsong.
Technique Elucidation
Interpretation and restoration of formulas.
- Rank B: Many astronomical and thaumaturgical texts, originally in Arabic, made their way to Europe through the translation efforts of Caster’s multicultural court.
Noble Phantasms
Juegos Astronomico
Pieces of Fate in God’s Gamble
Rank: E-A
Type: Anti-Unit
Range: Around a table
Max. Targets: Varies with each game, but seven players at the most
Two of the most influential books to come out of the Alfonsine court were the translated and expanded
Libro de los Juegos and the created
Alfonsine Tables, the first being an in-depth documentation of board games based on skill and/or chance, the first of its kind in Europe, and the second a compilation of astronomical data and positions. Casters sees the two as inherently linked, believing humans to be the pieces of the games played by the heavens, and of course the ultimate game the heavens play is war.
Caster owns a collection of hundreds of games, most prominently chess but with variants of backgammon and dice also included, and through the book’s expansion further, newer games can be collected. These games alone are not the true Noble Phantasm, but rather Caster’s ability to wager the fates of the players to the games, and a raised wager must be met.
Wagers can be simple, like a Luck rank increase by one for the winner and decrease by one for the loser, to more intense like the winner’s Luck being maximised and the loser’s being minimised, to the loser dying on the game’s completion. These games may be played against Caster himself, or against another Master or Servant with Caster acting as referee.
Siete Partidas
Rules for the Game of Kings
Rank: B
Type: Anti-Army
Range: Caster’s created territory
Of course, the obvious flaw with Caster’s first Noble Phantasm is that an enemy Servant can just refuse the game in the first place and attack Caster directly. This is where his second Phantasm comes in, based on his court’s third famous book the Siete Partidas, a law code whose impact is still felt today.
Through his synchronisation of games with astrology, within his territory Caster can make any game rule the rule of law, and that law being reality. Were chess rules enacted, one’s feudal class would determine one’s movement speed and direction. Servants’ stats would be randomised and rerolled under dice rules, and how many steps you could even take at a time randomised under backgammon. Being able to enact game rules upon his territory means Caster can also enact game penalties for rule breaking, such as damage, loss of mana, or sealing of skills or Phantasm depending on the severity of the rule broken, but he can also loosen rules for ‘good behaviour’.
In short, refusing Caster’s games is not your choice… at least inside his created territory. His first Noble Phantasm still has an advantage in that it can be used wherever. Were he summoned as Ruler though, this Noble Phantasm would apply to the entire vicinity of the Grail War.
Notes: Was originally gonna save this guy for Guess-A-Servant, but seems I couldn't wait that long, and it might've been slow going anyway since, outside maybe Spain, Alfonso X doesn't come up much anyway
