Timeflaying Blade

Timeflaying blades are forged around shards of collapsed paradoxes. Their existence is largely an enigma. In the furthest corners of esoteric scholarship, they're mentioned in passing or simply alluded to without ever being named outright. They're associated with Stethelos, the legendary city said to lie at the heart of the Dimension of Time, though it's unclear if they were made there, were discovered there, or are bound to return there at the end of time itself.

A timeflaying blade is a +3 greater striking greater corrosive keen quickstrike orichalcum bastard sword. Acid damage caused by a timeflaying blade appears not to be caused by liquid, but by the act of material simply eroding away into dust as if thousands of years passed in an instant (this doesn't impact a creature or object's acid immunity, resistance, or weakness, though).
