Fantastic Tribulation

The Fantastic Tribulation is a setting where the world has been through an event where supernatural forces (such as monsters from fantasy) bring chaos throughout Earth. This massive phenomenon renders society incapable of countering the event through conventional means. This leads to either an Urban Fantasy or an After the End scenario turning into a Cozy Catastrophe. Both, however, involve people gaining magic or some other form of mystical powers that are crucial to surviving in this new world.

An interesting trend has been seen in media like Korean web novels and webtoons. A common occurrence is having dungeons filled with monsters but they can be conquered by unique individuals. These people with powers counter these changes, thus giving way to stability. They are often connected to a system that functions like RPGs that can grant them these abilities and may be related to the society-changing catalyst. These people bring temporary peace by defeating them, including treasures, equipment, and mystical resources. Magic always plays a part as the cause or another tool for people to use.

If the setting becomes an Urban Fantasy, the society that comes into fruition has a new status quo or even benefits from the change. However, other problems may occur, not only from these forces but also from the people seen as protectors.

Contrast The Magic Comes Back. See also War in Heaven, which may precipitate this trope.
