The Nameless King

The Nameless King, Gwyns Firstborn or The Suns Firstborn was the lost named child of Gwyn and second yet short-lived King of Lordran.
== Lore ==
Shortly before the War of Souls and during the Age of Fire, in 45FA Gwyn had his firstborn child and in his honour, created the Four Knights of Gwyn.
=== The God Of War ===
During the War of Souls and when of age, The Nameless King begins to prove himself in battle. Wielding a mighty lightning imbued Swordspear, he slayed many a Dragon across the War and in 78AF, becomes revered as a God of War. He would make good friends with Dragonslayer Ornstein, with the latter effectively becoming the firstborns teacher.
As a newly crowned God of War, the Firstborn creates one of the worlds first covenants known as the Warriors of Sunlight, building statues and worshipping him as the Heir of the Sun.
Over time however, The Nameless King began to feel remorseful for the Dragons that he had slain and developed a deep sense of sympathy for them, slaying less and less as the War went on, but this was mostly kept to himself for the time being.
=== Warriors Of Sunlight Are Born ===
With the creation of the Warriors of Sunlight during the War of Souls, he began to teach his followers all that he could about his and his fathers power of controlling pure sunlight. These miracles of sunlight and lightning began to aid the war effort dramatically as Seath The Scaleless revealed that sunlight would help destroy the Dragons natural armour. A miracle resembling the Oath of the Warriors of Sunlight was also created in an attempt to strengthen the bonds between the warriors whilst fighting against the Dragons. He even constructed his own Ring, to prove his loyality to his father, whilst also strengthening his magical capabilities.
=== The King Who Lost Everything ===
Upon his fathers sacrifice at the Kiln of the First Flame, in 2FY The Firstborn became the King of Lordran and Anor Londo, wearing a golden crown and becoming the King of the Gods. With this newfound power and title, he began to express his sympathies towards the Dragons, an act that would not go down well with his peers. He began to order the end of the eradication of the Dragons, naming them allies and friends, even managing to tame one Dragon called The King of the Storms. 
In 7FY The Gods of Anor Londo then denounced the Firstborn, removing his deific title, exiling him from Anor Londo and destroying all knowledge that he ever existed, including the destruction of his covenant statues and his name removed from all records, before being banished from Lordran for all time. His ring he created in his fathers name however was left on his fathers mausoleum out of respect, before departing the lands, now a forgotten Nameless King. 
Not wanting to stand up against his former student and friend, Dragonslayer Ornstein leaves Lordran to pursue the Nameless King and join him on his journey.
=== A Nameless Kings Long Journey ===
Upon his exile from Lordran, the firstborn began to travel across the world, trying to find purpose once again with his trust ally, the King of the Storms. He decided that he didnt want his pact with the dragons mean nothing and so set out to construct a location hidden deep within the mountains to the North and making a haven for the Dragons, known as Archdragon Peak. It is unknown exactly when he created this haven, but it is known it was sometime following his exile from Anor Londo.
=== The Second God of War ===
During the transformative period in the years 45FY to 212FY, a self-proclaimed God of War, appears on the Eastern Continent of Dwyrain, but mostly in the country of Forossa. His symbol depicted a Knight fighting a Dragon as well as the ability to cast miracles. It was strongly rumoured that this was indeed the Nameless King, especially considering Faraam allied himself with the Drakeblood Knights of Higashi in 567FY and his construction of a Dragon Sanctuary on Dwyrain, similar to that of Archdragon Peak. It was however never proven as nobody ever saw Faraams face and most who knew the Nameless King were not there to witness him, so it still remains a mystery.
=== The Duel of the Nameless ===
In the long distant future in the year 1697FY, where even the thought of the Nameless King had long been gone, The Ashen One became the first human to enter Archdragon Peak where he then met the Nameless King. There the Ashen One and the Nameless king duel each other to the death, with the Ashen One first slaying the firstborns dragon the King of the Storms before beating the God of War in the duel, forever erasing the knowledge and memory of Gwyns Firstborn. The Firstborn never married nor had any children so this line of Gwyn was essentially finished, despite his long age and existence. The Ashen One also subsequently discovered the armour of Dragonslayer Ornstein, making it extremely likely that he did in fact find the Nameless King in his search for him, as well as being the one who created the secret warp entrance to the mainland from the mountain pack.
