The Heretic of Cleric Academy - Chapter 7

When he arrived in this world, many familiar stories had yet to begin: Sleeping Beauty had not yet been born, the magic lamp lay buried at the bottom of a treasure vault, Snow White’s father had just remarried, and the Little Mermaid was still playing in the sea with her sisters. In the heart of the desert, the Land of Oz had not yet welcomed the girl named Dorothy.Then he came—the wizard of miracles and wishes.…Many years later, even illiterate children knew his legend: If you find yourself in the darkest abyss or hold the most fervent desire, you might encounter a handsome boy cloaked in robes in a distant forest or lonely mountains.He is the omnipotent wizard, the all-knowing prophet, the sage revered by kings, and the mentor of legendary heroes. He gave Pinocchio life, granted the Little Mermaid an immortal soul, and heard the pleas of both princesses and beggars.Now, it’s your turn.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Rejected at birth for lacking Ka, the divine essence that flows through all living beings, Alioth seemed cursed from the very beginning of his new life.When the heavenly kingdom of the gods collapsed, the world was consumed by Azoth: an abyssal fog that mutates every living thing it touches.Humanity's last refuge became Caelestia, a colossal floating citadel built amid the ruins of the gods' former home.Here, lineage is everything. Those who possess superior Ka can demand absolute obedience from the weak. Without it, one becomes fragile and unable to wield magic.But Alioth harbors a hidden gift, born from his past life: the power to bestow names drawn from the myths of his old world.Zeus, Odin, Excalibur, Gáe Bolg. Everything he names acquires the legendary traits of its mythical counterpart.But will this power be enough to survive and decipher the mysteries of this world?Alioth doesn't know yet, but he's determined not to waste his second chance.
