Trivia

 * Commencement is the first and only base stage where the environment log is a fixed collectable rather than obtained from the randomly occurring Radio Scanner. High mobility is needed to reach the log which is underneath the boss' arena in the center hole of its base. Like the environment logs of the hidden realms, it will despawn if not collected within five minutes.
 * The name "Petrichor V" was originally a fan-name made up by the community. Now its canonically the planets name.
