Trivia

 * Commencement is the first and only base stage to not have to use a radio tower to get its environment log. All hidden stages are like this, but all base stages require the radio tower. The environment log for Commencement is in the base structure of the boss arena at the end.
 * The name "Petrichor V" was originally a fan-name made up by the community. Now its canonically the planets name.
