Poseidon

Poseidon is one of Kronos and Rhea's sons and a former leading god of Olympus. His pride and fear of the Black King's power make him one of Yeon-woo's earliest divine enemies, acting through Apostles and supported factions. The fall of Olympus and the loss of most of his power eventually force him to reconsider both Yeon-woo and the family grievances by which he had defined himself.

Biography

Divine punishment through Triton

Poseidon initially considers Yeon-woo as a possible Apostle, but turns hostile when he judges the player's conduct an insult to divine honor. He orders punishment and uses Triton, a violent clan backed by his holy power, to act first. His Apostle Benteke gathers Poseidon's Factors from the clan through Sea God Descent, concentrating them into a force that overwhelms Yeon-woo's more limited Channeling. The decision makes Poseidon's authority immediately dangerous while allowing him to attack from the heavenly world rather than descend without restriction. (Chapters 187–260, 272–279)

The plan fails because the same concentrated Channel creates a point Yeon-woo can drain. After taking Benteke's arm and learning the signature of Poseidon's power, Yeon-woo uses Bathory's Vampiric Sword to steal the Divine Factors sent through the Apostle. Other gods and demons block Poseidon's attempted descent, leaving him unable to retrieve Benteke. He loses so much holy power that his body withers and his standing is injured along with his pride. Poseidon's pursuit of punishment therefore strengthens the mortal he wanted disciplined and leaves the god personally weakened. (Chapters 287–299)

Opposition inside Tartarus and a final change of side

Poseidon next supports Paneth's party as Olympus' eyes in Tartarus, violating the brothers' agreement not to intrude on Hades' territory. He and the older generation fear Yeon-woo's wing of death and the Black King behind it, while Athena and Hermes protect Yeon-woo. As Olympus draws closer, Poseidon's blessing on Paneth's group strengthens, but the internal division prevents a simple united attack. His niece directly challenges him, exposing how concern for Olympus' old order has become conflict with the younger gods he expects to obey. (Chapters 362–382)

When Titans, Giants, the Demonism, and Mother Earth threaten Olympus itself, Poseidon's priorities change. He raises his trident and fights the invaders, later helps open the way to Erebus, and tells Yeon-woo—the successor to Hades' throne—to survive despite their enmity. Yeon-woo consequently remembers him not only as an early enemy but as a god who helped at the end. Poseidon's stand cannot preserve his old power, but it helps the surviving Olympians escape and gives his opposition a consequence more complicated than simple defeat. (Chapters 386, 544, 553–554)

A diminished elder reconsidering his family

Yeon-woo rescues Poseidon from Erebus, but Poseidon emerges with too little power to reclaim his former place. His last sneer at Yeon-woo becomes his final open resistance; pushed into Olympus' backroom as an elder, he initially dreams of revenge and then slowly recognizes the self-righteousness and haste that shaped his life. The loss of status creates a limit he could not accept as a supreme god, but it also gives him room to reconsider Kronos and Rhea as people caught in the same disastrous age rather than only as parents who wronged him. (Chapter 719)

When the defeated Zeus is returned to Olympus, Poseidon chooses to speak to him rather than reinforce his revolt. He acknowledges that diminished gods must either change or vanish into the past, and describes his own accommodation with the new order as a choice rather than domestication. Zeus rejects that conclusion, leaving the brothers divided, but Poseidon's response establishes his latest position: still proud and sharp, yet willing to live within Yeon-woo's Olympus and seek eventual understanding with Kronos. (Chapter 719)

Appearance and personality

Poseidon is described as broad-bodied, with a mane of hair befitting his forceful presence. After Yeon-woo drains his holy power, that body visibly contracts, bald patches appear in his hair, and dark circles mark his exhaustion. The altered appearance is not a new divine form but physical evidence that even a mighty Olympian can be reduced when a Channel is forcibly stripped of its Factors. (Chapter 299)

He begins with a vicious temper, a strong sense of what a god should be, and little tolerance for mortals who reject divine hierarchy. That pride produces both retaliation and poor judgment. Defeat does not make him gentle immediately: he resents Yeon-woo and laments his lost position before reflection changes his response. In later life, his bitterness is tempered by self-awareness, and he can laugh at Zeus's insult rather than answer with the fury for which his brother remembers him. (Chapters 250, 299, 719)

Abilities and powers

Seas, storms, and divine weather

Poseidon rules seas, water, and storms. Through his trident and holy power he can create tidal waves, raise violent storms, and exert influence even over the River of Souls, although that river belongs primarily to death-aligned gods. In a direct defense of Olympus, his raised trident produces storm winds capable of battering Titans. His water authority is strongest where an existing body of water gives his power a medium, not an unrestricted claim over every death-related or foreign domain. (Chapters 76, 277, 386)

Blessings, Factors, and Sea God Descent

Poseidon's Blessing rewards courage with greater buffs and defensive strength. Distributed across Triton, it protects ships and fighters through water-aligned holy power. Benteke's Sea God Descent draws the Factors shared with Poseidon's followers into the Apostle, increasing their destructive concentration and allowing a much larger flow of power than an ordinary borrower can Channel. This produces exceptional strength, recovery, and environmental control without making Benteke identical to Poseidon. (Chapters 275–279)

Channeling creates reciprocal vulnerability. Holy power can restore Benteke's body, but an injury carrying Yeon-woo's energy drain prevents the Apostle's severed arm from regenerating. Once Yeon-woo has sampled Poseidon's information, Benteke's transformation into a body of concentrated holy power makes the remaining Factors easier to steal. Other gods can also obstruct Poseidon's descent, so the blessing depends on a viable Apostle, a stable Channel, and enough uncontested power to pass between worlds. (Chapters 287–299)

Divine position and diminished state

At full strength Poseidon is one of Olympus' three ruling brothers, able to support Apostles, empower entire factions, and contest supreme threats. His power nevertheless rests on accumulated holiness, legends, and the society that sustains them. The losses around Benteke and Olympus visibly reduce his body, while the later war leaves him too diminished to resume leadership even after rescue. His latest state retains life, memory, and divine identity but not the level of force that once let him impose his will on Olympus. (Chapters 275, 299, 719)

Relationships

• Yeon-woo: Poseidon moves from considering Yeon-woo as an Apostle to trying to punish and stop him. After losing power and fighting in Olympus' final defense, he accepts Yeon-woo's rescue and rule without pretending that their history was friendly.
• Zeus: Zeus is Poseidon's younger brother and former king. They clash over Olympus' direction, and their later conversation contrasts Zeus's refusal to yield with Poseidon's hard-earned decision to change.
• Hades: Hades is Poseidon's brother and co-heir to Kronos' divided authority. Poseidon's agents intrude into Hades' Tartarus, but he ultimately recognizes Yeon-woo as Hades' successor and helps preserve that succession.
• Kronos: Poseidon helps overthrow Kronos and carries long-standing grievances against him. In retirement, he begins to see both of them as victims of their era and hopes for a future conversation rather than another contest.
• Athena: Athena opposes her uncle's campaign against Yeon-woo and directly checks him in Olympus. Their rivalry remains fierce enough that she later wins a standoff with him, but both continue within the same society.
