Keystones

A keystone is an object that pertains to a certain dimension, and acts as its keystone. It has existed since the creation of Reality, and comes from the Realm of Amon. They can be used as the ultimate key, as their atomic structures are insanely unique and hard to reproduce.

2nd dimension: a large obsidian rhombus, currently held within the Realm Tree. The Gelth, an omnipotent and omnipresent gestalt entity, currently lives within it.

3rd dimension: a human sized top heavy grey rock, currently in the Pagoda of Night, acting as the key to the Patchwork Man's cage

4th dimension: a fist sized cuboid blue crystal, imbedded into the brain of the Katineth's ruler. Key to the Time Wyrm's void iron cage in the Time Vortex.

5th dimension: a tiny diamond, at the core of the Katineth's world. If it enters the black hole that contains the Son of the Un-Named Blackness, it will disperse into hawking radiation, releasing it.

If all four keystones are brought together, they will form a fabled weapon called the Dalig Ulf-Stranden, a mighty gun impervious to the void or the time winds, that when given bloodstained tetrahedrons of paradox glass as ammunition, would transform each "bullet" into an n-ray. When the n-ray reaches a universe, the universe will become utterly twisted and corrupted, all live ultimatly serving the one who's blood covered the amunition in their cause. The Dalig Ulf-Stranden is a large misshapen grey rock with a tetrahedral hole, with a large jet black pyramidal protrusion. On the tip of the protrusion is a cluster of glowing blue crystals, and at the tip of the most forward-facing crystal is a thin two inch long glass needle.
