My Magic Is Absolute

Solace suddenly appears in front of a crowd with a throne in the very center. "Oh 4th Hero, you have arrived. Please help us with the battle of the Demon Lord." 4 Heroes were summoned with different abilities and skills. Solace or Sol later realizes that the magic in this world is really far behind. Knowing this, Sol decided to leave the heroes and become a rogue. Using his knowledge, he decides to build everything from the top. He was once the ruler of all, and he will do it again.
