the night circus

The circus arrives without warning. No announcements precede it. It is simply there, when yesterday it was not. The black sign, painted in white letters that hangs upon the gates, reads:
Opens at Nightfall
Closes at Dawn.

As the sun disappears beyond the horizon, all over the tents small lights begin to flicker, as though the entirety of the circus is covered in particularly bright fireflies. When the tents are all aglow, sparkling against the night sky, the sign appears - Le Cirque des Reves; The Circus of Dreams. 

Now the circus is open.
Now you may enter.
