The Beach at the End of Time

There’s a beach at the end of time. Most of the suns around the beach are dead and white dwarves litter the sky. The sun that warms the beach was one of the last suns to form in the universe. The beach is more than five hundred kilometers long and people come from all over time to get to that beach. There are a number of entry and exit points but one thing is a given; to enter the beach you must know magic.
