Just thought I'd see how well something like this would work after making sure we didn't have an active one already (or did I miss something) Rules are simple: One guess per person for every 5 posts, or if a certain time (let's say a day for now) has passed with nobody else guessing. Winner either makes a new riddle or passes. And obviously, please don't look up answers.

Guess I'll kick things off.

I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?
