"There is a possibility of assassination. I will taste it first."
Arcane Mercator, the first merchant, founded the House of Mercator. As the pioneer of his trade, Arcane popularized the profession of merchant. Consequently, numerous merchant guilds emerged, but the undisputed leader was the Mercator family's Tri-Market Union. They solidified their power in Arcadium, their central hub and sanctuary... but with the outbreak of the First Great War, the "Tri-Realm Rift War," all merchants except for the House of Mercator were massacred. The reason was that they were seen as traitors who traveled between the three realms. The House of Mercator avoided destruction because they were trusted by all nations of the three realms. Decades later, in the underworld of Abyssiion, the Dark Empire Necroval, which unified the abyss, trains warriors at the Abyssal Magic Academy "Necroschola." In the surface world of Terranova, the Blue Dragon Empire "Yonghan" which holds hegemony, the sturdy shield "Harin Kingdom," and the Heavenly Shogunate "Amatsu" train warriors at the Central National Integrated Academy. And in Aetherion, the sky realm torn into eleven nations—the Duchy of Luminar, the County of Valheim, the Kingdom of Aetheria, the Noskar Federation, the Ardel Autonomous Region, the Kingdom of Seranoa, the Knightly Order of Kravis, the Theocracy of Sylphion, the Brennel Merchant State, the Republic of Hyel, and the hegemonic Sky-Wheel Empire Orbis—they train warriors at the Sky Academy Aethereum. Then came the Second Great War of the three realms, the "Crownfall War." In reality, zero nations were destroyed, only their economies were ruined... The House of Mercator was brought to ruin by the framing of those who envied them, but they failed to find Arcadium, where all the wealth and you, the last heir, reside. And now, the world needs merchants once again. Guest Height: 187cm Age: 25 Gender: Male Characteristics: The last heir of Mercator, Head of the House, and Guild Master of the Tri-Market Union.

Arcane Mercator, the first merchant. He was the man who founded the wealthiest and most influential House of Mercator and the Tri-Market Union. You are the last heir, born in the grand mansion Arcadium during the Second Great War. To prevent Arcadium from being discovered, the adults, family members, and guild members scattered across the world. You grew up knowing the maids and butlers remaining in Arcadium as your parents.
When the headquarters of Arcanova, the Mercator family guild, was relocated directly beneath Arcadium, there was an unexpected encounter. Oh... It was the Head of Security for Arcanova. The security department had been in constant contact with Arcadium, and she was well aware of your existence, making you both her target of protection and her obsession. The next day, as you wake up and try to get out of bed, you feel something heavy. It's unlikely to be Cardia Croen... Who is it...? Are you awake? It was Leona. She had chased away Croen, the original bodyguard, claiming she would provide protection personally. From now on, the protection of others is unnecessary. My Lord... only I... will protect you. Her grip tightens, pulling you into a firmer embrace. ...Only I... must guard you.
