Item: The Keystones

The Keystones are a collection of temporal artifacts.

Overview

The precise number of artifacts in the collection called the Keystones is unknown; however, it is understood that, according to prophecies in the Book of Zemphitidus as well as hints from the Alazlai Manuscript, their appearance will be rather sudden, carried by a number of individuals whose "threads become untangled."

It has been deduced that the Keystones consist of a series of items that have suffered from massive temporal displacement, and that the Epoch Trigger in part led to their realization as temporal artifacts; prior to this event, they are unidentifiable as significant items.

Constituent Items

The Keystones, as mentioned, refers to a collection of temporal artifacts.

• The Sea Swallow, a swallow whose blades consist of metal from a pair of melted-down temporally-displaced bastard swords.
• The Green Amnesia, a music-box that made a rapid transit through multiple epochs in a short time span, leading to temporal distortion in its timeline.
• The Thirteenth Hour, an hourglass whose sand comes from beaches and deserts across time.
• The Chrono Trigger, a lance from the alternate timeline of the thran, used in the thran's creation of the temporal rupture to the Keystone Timeline.
• The Laulri Pendant, an elegant necklace whose centerpiece is a piece of nethicite.
• The Masamune, a katana forged from darksteel, a material that resists memetic detection.
• The Thread of Clotho, a silvery thread spun from the timeline, created by one of the first epochents.
• The Millenium Falcon, an intricate statue of a falcon carved from a meteorite fragment from the formation of the asteroid belt.
• Nalyd's Stopwatch, a simple clock imbued with temporal-displacement that was used to rescue the Toplanders from their temporal dislocation.
• The Mirror of Ages, a mirror whose surface is coated in quintessence.
• The Apocryphal Aegis, a battered shield whose construction was written out of the timeline.
• The Prophet's Quill, a simple, well-used quill used in the writings of various prophecies throughout history.
• The Millennial Meme, a meme crystal containing a incredibly mutated viral meme constructed from the various "end of the world" beliefs across time.

Item Abilities

Each of the Keystones has an array of abilities, though passages from Zemphitidus imply that not all of their powers will be unlocked at the Epoch Trigger; Zemphitidus makes a number of cryptic references as to how to unlock the items, though current theories suggest that the items must experience a number of particularly important events, including their own creations, in order to fully unlock the secrets within them.
