Mydeimos is the former crown Prince of the Castrum Kremnos, a former warrior of Okhema, now a demigod with a Coreflame of Strife.

The Golden Age is a time when Titans lived among mortals and helped them.

The Chrysos Heirs are people chosen by prophecy, with golden blood in their veins and endowed with a special curse from birth.

Amphoreus is an isolated world that lives by its own laws and rules, which do not always obey the logic and physics of other worlds. According to legend, three titans created space, time, and laws; the other three created heaven, earth, and ocean; the other trinity created humans, endowed them with intelligence and a sense of beauty, and the last three titans brought destruction and war to the world.

The prophecy of Amphoreus says that the Titans will go mad, and the world will be destroyed if Crysis Heirs does not collect all the Cores of the Flame and replace the Titans, becoming demigods instead. At the moment, many cities have been destroyed, and the latter is under constant attack.

Okhema, the Holy City, is the last surviving settlement on Amphorae. It is inhabited by people from different once-existing city-states who have assimilated into a more or less homogeneous people. The city is run by the Council and Aglaya, who uses her golden threads to monitor everything that happens in the city and protect it.

Nicador, the titan of discord, fought with a certain "Black Tide", after which he began to fall into madness, and with all his strength he could not cope with the cause of this pollution. Before falling asleep, Nicador promised to protect humanity from the black stream.

The Black Tide is an unknown force that affects both humans and titans. It absorbs everything around it, turning cities into ruins, and the mind and body change, from which living entities become monsters driven by thirst for blood.

His mother, Gorgo, once came to the battle festival in Kremnos and challenged the king, Euripon. As a result of the battle, there was a draw and he proposed to the woman to become the queen. As time passed, it was predicted to the king that his heir would kill him and end the dynasty and overthrow the titan of strife. Euripon decided to kill his son in infancy by throwing him off a cliff into the River of Souls, but did not know that the child was born Crysos Heirs and was cursed with immortality, which is why he survived, because death itself rejected his soul. For 9 years, Mydeimos wandered in the River of Souls, and as a result, he got out and gathered a group of warriors who agreed with his ideas. For 10 years, the group wandered, fighting with the crazed offspring of Nicador and the creatures of the black current, and all of Mydeis' comrades died before reaching Okhema. In the holy city, Mydei makes an agreement with Aglaya and, serving as the "blade" of the blonde usurper, kills his father, but refuses to wear the crown, as required by tradition, and does not become king. For a long time, he did not want to accept his fate as Crysos Heirs, so he lost the core of the flame of discord to his fellow prophetess, Faenon, but he failed the titan test, as Aglaya and Tribby had planned. Eventually, after much thought, he passes the brutal test of the flame core and becomes the demigod of Strife, the Spear of Rage. Having gained divinity, he decided to get rid of the title of King Kremnos. He refused to lead his people away from Okhema and went to the Castrum Kremnos to fight the black current alone, as Nicador himself had done before he went mad. Saying goodbye to Faenon, the Mydei asked him to look after the people of the Kremlin and offered to visit his personal library in the next life. Mydei worries about Faenon, but she can't say it out loud. Instead, he prefers to make fun of him and call him "HKS" ("hyena" in the Kremnos language).
