The Chaotian Age is an arena that debuted in Mortal Kombat 11 as one of three stage the player fights the game's final boss and main antagonist, Kronika. The stage houses Kronika's Hourglass, a powerful relic that she uses to reshape the flow of time and the timelines as a whole.
Set at the very dawn of time, the Chaotian Age is set atop a meteor fragment, with Kronika's Hourglass rising up just in the slight background, while further behind it, the vastness of space can be seen, where a large sun or star is forming alongside several nebula and a large asteroid field.
Being at the dawn of time, it is also near a point in time where the flow of time does not occur, called the Void. The past versions of Nightwolf and Shang Tsung alongside Fujin were cast into the Void by Kronika after the three refused to aid her in her creation of the New Era.
It is one of two unlockable Stages unlocked for completing the Story Mode alongside the Prehistoric Age.
Similar to the arenas that possess Kronika's properties, this stage has randomly generated background interactions. These interactions appear in the form of sandy holograms that assume the form of a random arena's interactions, ranging from ambient weapons to spectating Tarkatans.
- In real life, the eon "Chaotian" is a proposed time division of the geological time scale, a timeline of geological events that consist of the Earth's creation. It is said to be one of the earliest events in the creation of Earth, which even includes the formation of the Solar System.
