Grace Sherwood's Sickle

Origin
Also known as "The Witch of Pungo", Grace White Sherwood was the last person to be covicted and tried of witchcraft in the colony of Virginia. She was known in the community as a respected healer prior to her convictions, and reportedly had extensive knowledge on various medicinal plants.

Accusations regarding witchcraft started with rumours that she had made livestock sick and crops die. Though she sued the accusations, she was fined and imprisoned in 1706. Released in 1714, she returned to live on her family farm untilher death in 1740.

During a short-lived stint as a Warehouse clerk, one agent released information on several artifacts to a noted game developer he was fond of, Tetsuya Nomura. The agent was fired, but Nomura used this artifact as the basis for the Kingdom Hearts character Marluxia's weapon.

Effects
Holding the sickle over a crop or plant causes it to grow strong and bountiful, increasing the nutritional and medicinal properties. In order to do this, the sickle drains nutrients and sustenance from other plants. For a sufficently large crop, animals may also be drained of energy until dead.
