A crown hammered from the light of the first star of a Void where the stars burn for a few short years before collapsing into scalding vitreous lump; the glow it exudes with white-hot and fierce, never dimming or dulling, cutting through any covering less than a box of lead and scattering all dust and mist before it.

A set of delicate-seeming items, which each gently radiate light and sound as if they were, somehow, the birth of a cosmos constrained into these forms. One can use them to tweak the fundamental states of existence, although none can wholly rewrite any cosmic law with them; the roll that holds them, made of some unknown leather, does seem to have places for nearly a dozen more of varying sizes.

A box somehow cut from the blacker-than-black firmament of a Vault, almost weightless and yet possessed of immense inertia; opening it reveals a piping hot strawberry danish, fresh from the oven, no matter what. Careful examination will reveal a wobbling temporal loop within, which formed with the pastry's arrival, which completes and resets each time the box closes. It seems likely that thousands, at the very least, of iterations have happened, and those snipped-off fragments of time might be what lends it such inertia.

A bottle capable of storing up to one day of time, which can be used to perfectly refresh and experience the memories of the day anew, without the vagaries of memories softening and blurring them over the passage of time. If one experiences a better day, the old one can be poured out and replaced, but you should be sure to wipe the interior out thoroughly first lest a bit of the older one mix into the new to create minor paradoxes.
