Disk of returning

The disk of returning is an item obtained by beginning a midsummer ritual during midsummer events.

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. Occasionally when dropped, the chatbox messages states "Something cool happens." and the player performs the dance emote. These are references towards the original date on which they were created, where players could visit the black hole and use their disk of returning to go out; other players would tell players that "something interesting would happen" and they couldn't get out of the black hole resulting in many players getting trapped.
 * Note: You can still get out of the main black hole where Thordur resides even if you do not have the disk of returning in your inventory.

Trivia

 * During the summer of 2013, it was obtained by killing the high priest in the Goblin Invasion event located in the Varrock castle courtyard.
