Xanesh open rifts to the Void causing several players to become Voidwoken, and summoning an orb that drifts towards Queen Azshara.
Voidwoken players can redirect the orb by colliding with it, causing the orb to drift in the direction they are facing.
If the orb reaches an open rift, it is sent back to the Void.
If the orb collides with a non-Voidwoken player, they suffer Revile. If the orb collides with Queen Azshara, a ritual obelisk, or the edges of the chamber, it causes Dark Collapse inflicting 60.0464 Shadow damage to all players.
