- "Zone of Silence" redirects here; you may be looking for the Zone that was merged with it to create the Special Zone in the original continuity, The Void.
The Special Zone is a zone which was formerly the location of the seven Chaos Emeralds, and once acted as a place of banishment for Nigel Acorn and Walter Naugus when Dr. Eggman took over Mobotropolis.
The zone has been visited by Sonic the Hedgehog and his friends on a number of occasions, usually in order to gather the Emeralds.
A King's Prison
When King Nigel Acorn's royal adviser, Dr. Eggman, betrayed him and took over Mobotropolis, the dictator banished the overthrown King into the Special Zone along with the royal wizard, Naugus. During his first adventure to libertate South Island, Sonic ventured into the zone several times, where he was not only able to rescue (supposedly) King Nigel, but gather the first six Chaos Eneralds. After realising their first rescuee was really Naugus in disguise, the Knothole Freedom Fighters later managed to rescue the real King from the zone upon taking back Mobotropolis.

The Special Zone is evidently a mystical dimension that is difficult to escape, as even Naugus proved unable to break free from it with his magic.
The physical appearance of the zone supposedly differs to some degree. After his visits to the zone, Sonic described its environment of consisting of "crystal mazes that spun around" and a sky "that keeps changing into all these different shapes". (StH: #288)
- The Special Zone originates from various Sonic videogames, which could be played either between or during zones (depending on the game) and, if cleared, would award the player with a Chaos Emerald.
- Sonic's description of the Special Zone after his first few visits correspond to how it appeared in the original Sonic the Hedgehog game for the SEGA Genesis.
