A Proof Fragment being collected in the Archwing mission in Mars.

Proof Fragments are quest items required to construct the Limbo Theorem key (not to be confused with the quest key).

Acquisition

They can be obtained by killing the enemies from the quest, where the fragments take up the form of Nav Coordinates. A total of 9 fragments are required to build all the keys needed to complete the quest.

Characteristics

Supposedly, these fragments transmit the signals all across the system and may be found by investigating the wavelength. It is described by Ordis that the frequency--while constant, is far too weak to be caught by the Orbiter's antenna and that it would require a sophisticated antenna to fully catch the wave such as the satellite found in the Archwing Interception mission.

In a way, the Proof Fragments themselves can be interpreted as the remains and the relic of the original  Limbo in the form similar to cosmic background radiation, as the fragments can be engineered into a theorem which leads into another Limbo piece.

Proof Fragments can be sold from your inventory for 750 Credits 750 each. Any Fragments beyond the 9 needed to complete the quest can be safely sold.
