“I found one account of the Long Night that spoke of the last hero slaying Others with a blade of dragonsteel. Supposedly they could not stand against it.”

“Sam, we tremble on the cusp of half-remembered prophecies, of wonders and terrors that no man now living could hope to comprehend . . . or . . .”
“Or?” said Sam.
“. . . or not.” Aemon chuckled softly.

What is dragonsteel? This has been a mystery ever since it was first mentioned in A Feast for Crows. Jon Snow and Sam both suggest that it is most likely a reference to Valyrian steel, but that is all it is – a suggestion, a hypothesis.
Can we actually determine what it is? If so, can we derive any compelling speculations on just what kind of weapon we’re looking for?
I believe the answer to both questions is a definitive and resounding YES. I believe in three ideas:
Dragonsteel is actually silver.
Lightbringer is not a weapon at all.
Yet it is the key to ending the conflict with the Others.
