Waiter from Nowhere

Humans, peacefully living on the planet named "Earth". For millions of years, there's no occurrence that happens in the year 2026.

Year 2026

A huge earthquake shocked the whole world. Everyone is not ready for this event. A 7.5 magnitude earthquake throughout the whole entire world.

Tsunamis, hurricanes, volcanic eruptions, lightning all over the world.

While everybody is busy trying to survive that event. Some people notice a thing rising in the ground. A tall tomb-like building rising in the ground.

A "Dungeon" that is what you're gonna call them through in this story.

All the people who survive the catastrophe rebuild the economy through the years. People help each other trying not to give up and lose hope.

After that, all the people in the world call it "Dooms Day" and it became a holiday all over the globe. And they've become aware that it may be repeated and even think that the Earth will perish.

Some of the country, Dooms Day is a festival, they're gonna party like it's the end of the world. Some of them were frightened, some of them became fateful to the Lord, some of them just gave up saying to themselves "Everyone's gonna die when it comes, the Dooms Day"[Not sure though]

After 10 years of that horrific event. Another occurrence that never happened in the past millions of years.

Humans can use mana but not all of them. Mana can manipulate all the elements. Water, Fire, Earth,Wind, Light.

It is common for humans to have one element that can be manipulated. Two elements are unique, Three elements are rare, 4 elements are gifted.

There's no record on human history that can manipulate all the elements. Also, there is no human that came out after entering a dungeon even though they can use mana.

"What is in the dungeon? Are there monsters living there? What do they want? What is the purpose of the dungeon?". All of these are the questions of the masses. Still have no solid proof answer from the government.

10 years after the Dooms Day, everyone returned to their normal life. Dungeons are like building in the past. It's just a tourist attraction or artifact that nobody can explore or explain.
