The Guild's reason for existing is tied to the Silver Crown, a precious artifact found in the town of [[Sirvarris]] shortly after the town was resettled, alongside a medieval-era [[greatsword]] and a document written by King Maratuxa, the last ruler of the Silverlight Kingdom, which ruled the world throughout [[History of the Mazes|Era 4]]. This Crown was incomplete, missing a large mounted diamond. The document explained that King Maratuxa's last wish was for the Silverlight Kingdom to be re-established for the future. To do so, he hid the kingdom's treasure in a secret cache somewhere in the Mazes, locking the doors with a special lock, which can only be opened with one "key": the Silver Crown itself. However, the mechanism will not work if the Crown is incomplete. To open the cache, the Silver Crown must be reunited with its Diamond and inserted into the lock. The first person to do so will gain access to the treasure within and use the wealth to re-establish the Kingdom.
Shortly after the Crown was discovered in Sirvarris, roughly 650 years ago, it was stolen; the act was revendicated by a gang known as the Wraiths, responsible for the [[History of the Mazes|Twin Terror Acts of E7-54]]. After the eventual defeat of the Wraiths in E7-55, the Silver Crown was never found among the Wraiths' assets, and as of today, remains missing.
The Guild was established for the purpose of finding the Silver Crown, reuniting it with its Diamond, then finding the secret Silverlight Kingdom's treasure. As of today, all three are still missing.
