Shrine of Serendipity
Shrine of Serendipity, because it is consistently referred to as such in the actual story.
Talk about it here.
The Shrine of Serendipity was one of the many religions represented in the Multihaven. As their name implied, they praised happy accidents, however, they also believed that all accidents were happy, so would even react with glee to inconveniences or physical injuries. Their god was the Lord Whoops, known as "the Great Neglector". As the church's members embraced accidents and chaos of all kinds, their credo was "may your way be strewn with obstacles", which was seen as well-wishes. During the attempted takeover of the Multihaven by the Lucidians, most Serendipitists were either brainbleached or went into exile. (AUDIO: Faith Stealer)
