The Black Massacre

"News of a certain person named Black has spread across the world of Arc. Many report sights of him killing innocents one after the other in major cities and settlements, a cackling and soul shattering laugh echoing through the carnage. If nothing is done about Black soon, the death toll will continue to rise. Officials in the moonlight continent urge everyone to keep an eye out for a very tall, slender person dressed in black with a one-handed broadsword at his waist and a mask with a large smile. People on the Hope continent are warned to proceed with caution as well."

This arc was brought to a close when Jenna Liddell brought certain memories into Black / Yggdrasil's mind. Black had then voluntarily let himself be sealed, leaving behind his blood, which according to him, can be used for a variety of purposes to help rebuild what he had destroyed.
