|City of Silver Pocket Dimension|
|Primary Residents||Kestora, City-Building Creatures, the Spectral Mask|
The City of Silver Pocket Dimension is a pocket dimension of the Matoran Universe.
Due to the effects of Brutaka's damaged Kanohi Olmak, Takanuva was transported to a pocket dimension with a dead forest, where he encountered a floating Spectral Mask. The entity told him about a city in danger and Takanuva rushed off to it before the Mask finished talking. He arrived at a city where he found several small purple and black beings called Kestora fighting against a creature that resembled an Archives Mole. Takanuva thought the larger creature was the source of the fight and drove it out. After defeating the creature, he was locked out of the city by the Kestora. Afterwards, he sought out the Mask, who told him that he had actually defeated the last inhabitant of the city. Realizing his mistake, he searched for the creature and convinced it to trust him. After some planning, Takanuva created a fireworks show which lured the Kestora out of the city and let the large creature in, allowing it to lock the Kestora. Takanuva then returned to the Spectral Mask, who congratulated him and opened a dimensional portal that transported him to an alternate universe.
Only two locations are known in this Pocket Dimension.
- City of Silver - A city made of silver and crystal towers which belongs to large creatures. Another species called Kestora temporarily took hold of the city, but it has since been returned to the one surviving creature by Takanuva.
- A Dead Forest - Outside the city lies a dead forest with bare trees. The Spectral Mask resides there.
Only three species are known to inhabit this dimension.
- The Spectral Mask - A floating entity resembling a mask
- The City-Building Creatures - The builders of the City of Silver and a seriously endangered species. Greg Farshtey has since confirmed that there were other City-Building Creatures still alive on the planet, they had simply left for the time being 
- The Kestora - A race that attempted to take over the City of Silver.
