A player inside Thordur's blackhole.

The disk of returning is a rare item that was obtained by killing the high priest in the discontinued goblin invasion event located in the Varrock castle courtyard. To receive a disk of returning, players had to deal some damage to the high priest.

Activating it requires the player to be inside the Dwarven Mine, and when activated the player teleports into the Blackhole, where Thordur resides. To leave, simply activate the disk again.

Attempting to drop it will result in a confirmation message "Yes, something cool might happen." However when dropped it will simply say "That was disappointing.", indicating nothing will happen when dropped.
