Silence

Silence is a planet in the F-Zero series, aptly named so due to the fact that nothing on the planet creates any noise. Absolutely no life can be found on this planet. According to F-Zero GP Legend, no living creature calls this place home, which is why this world is deserted.

In the original F-Zero, this course consists of 90-degree curves, and a shortcut with mines. There was also a circuit in BS F-Zero Grand Prix 2's Ace League, named Silence II, in which the original track was expanded while also adding Jump Plates at guardrails in certain intervals, as well as a risky large gap in the epicenter with its edges covered in them.

In F-Zero X, Silence appears twice: the first one in the Jack Cup is a straightforward banking course with Dash Plates, the second one in the King Cup is narrow with many sharp turns and a wavy section with no barriers.

Ikran's F-Zero timeline
It was mentioned that this world housed the final course of the Knight League during the original Grand Prix, in which Tinsel won second, just almost beating Capt. Falcon who took the gold.

It only made a single appearance in Ending it All, in which Leon has a nightmare created by The Skull's black arts at Dark Star. At the Ace League's course, he faces off with a doppelganger of his along with remote-controlled machines that looked similar to the ones he knew, only there were no pilots, and functioned as deadly bombs. By a stroke of luck, Leon won the race for the orphans and children of Planet Zou; however, he soon realized none of it was real.
