Located at the nexus of every possible timeline, the Temporal Singularity is a place where the laws of physics are mere suggestions and the concept of causality is but a distant memory. It's like the Grand Central Station of Time, where all trains arrive and depart simultaneously, yet never actually get anywhere.
It's said that only a select few have ever managed to navigate the Singularity, and even fewer have returned to tell the tale. Those who do often speak of a realm where time is currency, and the rich live forever, while the poor are stuck in an eternal loop of Groundhog's Day.
If you're feeling adventurous, you can try to time travel through the Singularity and see where it gets you. But be warned, the experience can be... enlightening.
Or, if you'd rather not risk losing your mind, you can read about others who have attempted it.
