Malmord

The Malmord is an ancient Sheikah artifact that seals those who come in contact with it within a world or plane of existence separate from Hyrule. The artifact was used by the Sheikah as a magical prison in ancient times, but has since been outlawed. The Malmord appears as a glowing golden sphere vaguely similar to the Eye of Truth.

Etymology
Malmord is an Ancient Hylian term for "Fate Keeper."

History
The Malmord first appears in Mission 27: "Of Princess and Portents" where it is stolen from a Sheikah Fortress by Azrily for Lord Akazoo. The two plan to use it as a sanctuary to survive the Gohma infestation of the Kingdom of Hyrule un-consumed. Azrily later uses it to trap Tetralyna Zelda V at Akazoo's behest.
