"The House Beyond Your Sky", Benjamin Rosenbaum

SS Strange Horizons September 4, 2006 – science fantasy)
A powerful yet compassionate priest called Matthias has a library that contains worlds such as our own. He is building a bubble universe behind his house. A pilgrim from far away, one of the ancient ones, visits Matthias and wants to become ubiquitous in Matthias's new universe. Matthias hides his keys from the pilgrim.

I found this short story rather odd, and I couldn't get into it. The plot line in the world like ours, with its scenes of domestic violence, was a bit unsettling. I guess I'll give brownie points to the author for writing something different -- a tale about God-like universe-spanning beings -- and for some clever phrases.
