|“||Who dares disturb my prayer? Impious fools! I am the High Priest Hargon! Knowest thou not my name?||„|
High Priest Hargon is a corrupt cleric, the one responsible for the destruction of the Kingdom of Moonbrooke, the resurgence of monsters in the world, and the main antagonist of Dragon Quest II (previously known as Dragon Warrior II). He reprises his role as the main antagonist in Dragon Quest Builders 2, serving as the enforcer of the hegemonic sect known as the Children of Hargon.
Seeking to summon The Master of Destruction, Hargon has sent his minions to siege various settlements. His minions attack the Kingdom of Moonbrooke, where the King attempts to save his daughter but ends killed along with everyone. The Princess of Moonbrooke; a descendant of The Legendary Hero, Erdrick, manages to escape the assault but ends up cursed into a dog form. An injured knight manages to escape the burning castle and deliver the news to the King of Midenhall before perishing, so the King sends his son, also a descendant of Erdrick, to go after Hargon and stop his plans.
The Prince of Midenhall joins forces with the Prince of Cannock (also a descendant of Roto), and the two break the curse upon the Princess of Moonbrooke, who also joins them. The trio travels the world and defeat all of Hargon's minions, eventually confronting Hargon himself in his castle at the Rendarak (Rhone in the NES version) region. Upon being defeated, Hargon offers his own life as sacrifice to Malroth, which is finally resurrected as Hargon dies.
