Plague ball

The '''plague ball" was a magical artifact created by Whistler, Pearl, and Nash in their efforts to "save" the world after the failure of Twilight.

Using the residual magic from several items, Whistler, Pearl, and Nash formed the ball to spread a magical plague across the world. In the ensuing skirmish between themselves and Angel and Faith's group, Giles knocked the ball out of Nash's hands with a fireball. Despite their attempts to catch it, the ball exploded over the streets of Hackney, London, painfully transforming numerous humans below into mutants and monsters.
