Unfinished Vault

the Unfinished Vault, also known as Vault Zero, was a Roblox meeting-place and server used by a group of early myth hunters and exploiters. Used during the winter of 2006 and 2007, it was believed to be used for experimental purposes.

History
First built in November 2006, the Unfinished Vault originated as a baseplate devoid of features. However, as more strange occurrences swept Roblox, it turned into a meeting place for the creator and a group of friends to discuss the development of new technology within the platform.

In the winter of 06-07, the Unfinished Vault was involved in the study of the strange phenomena known as Phantom Posts. It also was responsible for testing experimental scripting, some of which may have been used as the base of early exploits. Somewhere around this time, the Vault was moved to a special holder account.

By mid-2007, it was planned for the Unfinished Vault to be completed and turned into one of the most high-quality Roblox places. But before this could take place, nearly all traces of the Vault and it's holder account disappeared, and most forum posts about the vault were deleted after the first minute of posting.

Fate
It is unknown what truly happened to the Vault and its userbase. Some think that 1x1x1x1 may have been associated with the Vault and its disappearance, while others think it may be related to their research into the Phantom Posts and other anomalies. Regardless, it is generally believed that something sinister was at play.

It is unknown if the Unfinished Vault is related to the Vault 8166 rumor, but it must be recognized there are notable similarities between the two.
