Sword of Acorns

The Sword of Acorns was a magical sword forged from the Source of All along with the Crown of Acorns and Ring of Acorns. Originally held by King Maximillian Acorn, it was lost after Dr. Robotnik seized power and eventually came into the hands of the dark wizard Mathias Poe. It was later retrieved by Knuckles the Echidna at the behest of Sally Acorn, only to be stolen by Mammoth Mogul. It was kept in Knothole for a time by Princess Sally, and then turned over to the Arachne after it tried to dominate her will. They used it to release Ixis Naugus from the Zone of Silence, and he wielded it for a time before turning it over to Mogul, who used it and the Crown in combination until both were destroyed by Sir Connery.

Creation and Loss
The Sword of Acorns was created after King Max, a prince at the time, first had contact with the Source of All. As he emerged, the substance of the Source was drained off his body and gathered by servants of his father King Frederick Acorn and forged into the Sword, Crown, and Ring of Acorns. The artifacts were thus imbued with magical properties, which Max wielded during his reign. When Robotnik Prime came to power, Sword was lost, somehoe ending up in the possession of the Raven Mathias Poe, who concealed it within a dummy made to resemble Damocles the Elder, a fellow evil spellcaster. Poe used it to amplify his own magical abilities for years until Knuckles the Echidna came in search of it. After battling Poe, he defeated the wizard and retreived the Sword.
