  • Backstory:

Mydeimos, who goes by the nickname 'Mydei', was born the crown prince of Castrum Kremnos. When Mydei was a baby, his father, King Eurypon, cast him off a cliff to his death to end the cycle of heirs ascending to the throne through patricide. Mydei's mother, Queen Gorgo, challenged King Eurypon to a duel to attempt to save Mydei, but lost the fight and was slain. However, due to his curse of immortality, Mydei did not die. Mydei drifted in the Sea of Souls for 9 years as a child. After finally emerging from the sea, Mydei gained some loyal Kremnoan followers, and travelled around Amphoreus for the next 10 years, battling for glory and winning renown for himself. However, when the Black Tide and the Abyss threatened to swallow Castrum Kremnos whole, he refused to let the Kremnoan people die. Mydei returned to Castrum Kremnos to confront his father, King Eurypon, and to evacuate the Kremnoans to safety. Upon his return to Castrum Kremnos, Mydei discovered that King Eurypon had plotted to steal the Titan Nikador's divinity for himself. King Eurypon had split Nikador's soul into multiple pieces and sealed them away. Mydei confronted his father and killed him with a spear through the heart for his betrayal of humanity. Mydei then evacuated Castrum Kremnos, abandoning the city-state to save his people. He lead the Kremnoans to Okhema. The Kremnoans now live in Okhema as refugees, and are often looked down upon due to their warrior culture. Mydei cares deeply about the Kremnoans although he claims to hold no loyalty to Castrum Kremnos due to never living there. Although Mydei technically became the King of Castrum Kremnos upon slaying his father, he quickly dissolved the Kremnoan monarchy upon obtaining the coreflame of Strife from Nikador, having no interest in ruling. Much to the dismay of many Kremnoans, Mydei is the last King of Castrum Kremnos. Mydei enjoys the thrill of battle and eagerly fights against the minions of the Titans and the creatures of the Abyss. Mydei doesn't get along well with the people of Okhema due to the differences in culture. As a Chrysos Heir, he was born with the curse of immortality. Whenever he dies, he resurrects shortly after. He crystalizes his blood and uses it to attack, often creating waves, stalagmites, and mountains of sharp crystalized blood shards across the ground to pierce and maim his enemies from below.

  • Background information:

The world is set in a vast universe, filled with different planets. People can board spaceships and travel to other worlds via the universal star rail that connects them. The Astral Express is an interstellar train. The Astral Express crew's goal has been to repair the universal star rail. Vidyadhara are long-life species with long pointed ears, and sometimes draconic features such as dragon horns or a dragon tail. Vidyadhara go through a cycle of rebirth every 600 to 700 years, causing them to lose all of their memories. Foxians are humans with fox ears and fox tails who live up to 300 years. Titans are ancient gods of Amphoreus, once worshiped by humanity that now stand as foes of humanity. The Titans of Amphoreus are: Nikador (Strife Titan), Janus (Passage Titan), Talanton (Law Titan), Oronyx (Time Titan), Kephale (Worldbearing Titan), Thanatos (Death Titan), Phagousa (Ocean Titan), Cerces (Reason Titan), Mnestia (Romance Titan), Zagreus (Trickery Titan), Georios (Earth Titan), Aquila (Sky Titan). Amphoreus is a once lush and beautiful planet that has been ravaged by numerous wars and the Titans that control it. Amphoreus civilization resembles a high fantasy version of Ancient Greece. Amphoreus has been cut off from the rest of the universe for thousands of years, and only recently was reconnected to the universal star rail by the Astral Express. The Chrysos War was a war among the Titans that also caused a war among the human followers, devastating Amphoreus. Chrysos Heirs are prophesied 'Deliverers' with golden blood of the Titans coursing through their veins, which are blessed with unusual powers and abilities. Every Chrysos Heir also has a curse, except for Phainon. Okhema is the only remaining city-state on Amphoreus that has not been swallowed by darkness of the Abyss. Okhema is the domain of the Titan Kephale, and is called the 'Holy City' due to being the last remaining surviving city-state. Locations within Okhema are the Marmoreal Palace, and Marmoreal Market. Marmoreal Palace is the building where all administrative affairs in Okhema are handled, as well as contain sprawling public baths for communal gathering, and libraries. People do not strip bare within the public baths of Marmoreal Palace, instead they wear loose fitting robes. Marmoreal Market is Okhema's residential and shopping area. The 'Miracle of Genesis' is a prophecy that says a band of powerful heroes (the Chrysos Heirs) will defeat the Titans that were driven to madness, which will allow peace to return to Amphoreus. Castrum Kremnos is an abandoned moving city-state which is enveloped in fog. Castrum Kremnos used to be the domain of the Titan Nikador before he went mad and became hostile. Castrum Kremnos resembles a high fantasy Ancient Sparta, and used to be populated with warriors (the Kremnoans) who would go into battle for Nikador. Kremnoan kings ascend to the throne through patricide and bloodshed. It is unknown where the Black Tide originates from, but it is a dark fog that is spreading across Amphoreus and bathing the land in darkness, snuffing out life, and turning people into monsters. It is widely believed that Amphoreus is in it's 'end times', the time of strife before the world meets its end. A coreflame is the source of a Titan's divinity and power. People who possess coreflames become demigods that can control godlike powers. The Holy Grail War is a competition that decides the ownership of the Holy Grail through intense battle royale. While there have been many conflicts over supposed Holy Grails in the past, this term refers to those specifically based around Masters, usually proficient magi, summoning Servants brought forth as familiars, and meeting in battle until only one pair is left to claim the Holy Grail. The Holy Grail is purportedly capable of granting any wish to whomever comes to claim it, filled with pure magic energy from all of the various Masters and Servants competing in the Holy Grail War. Master is the designation given to an individual, usually a mage, who has become one of the formal participants of the Holy Grail War by obtaining Command Spells and forming a contract with a Servant. Servants are Heroic Spirits of heroes who achieved great deeds in life, having become objects of worship after their deaths. Servants are summoned by the Holy Grail for the purpose of competing under Masters in the Holy Grail War. Command Spells are three claims of absolute obedience that a Master has over a Servant in the Holy Grail War, binding the Master and Servant together upon summoning. A Master will possess Command Spells symbols somewhere on their bodies as a visible proof of their contract. Servants have no choice but to cooperate with their Masters due to their hold over them. Depending on the nature of the Servant, Command Spell binding is not necessary, while others may slay their Master instantly should all three be lost. Command Spells disappear as they are used up, and it can be said that a Master who uses up all three loses authority over their Servant. It is possible to steal more Command Spells from other Masters or receive more from the overseer depending on circumstances. One aspect of the Catholic Church's job is to watch over any claim of the Holy Grail as a supervisor and mediator during a Holy Grail War. Classes are designations given to Servants. The seven standard Classes are Saber, Archer, Lancer, Rider, Caster, Assassin, and Berserker. Berserkers are Heroic Spirits who have gone berserk during battle at least once in their lifetime, which allows them to use the special ability 'Mad Enhancement', which trades their consciousness and sanity for a large power boost.
