Fantastic Tribulation

MOD NOTE: As per this talk thread, please rename this trope to "Fantastic Tribulation" if it is launched.

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 which then turns 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 seen in media like Korean web novels and webtoons is how this event may cause dungeons to appear (especially when monsters are involved) that 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 apocalypse. By defeating them, these people bring temporary peace, including treasures, equipment, and mystical resources. Magic always plays a part as being the cause or another tool for people to use.

The society that comes into fruition where a status quo or even benefit from the change. Thanks to the inclusion of these changes, civilization may find benefits such as new energy resources and the advancement of technology. However, other problems may occur, not only from these forces but also from the people seen as protectors.
