From the crystal's description - as well as it's "Force focusing" properties - I was always under the impression that it was the forged from the remnants of the Sith amulet/s that Kun was famous for wearing, since that was the obvious tool through which he amplified his power.
Of course, the amulets had pink gems, whilst the crystal is cyan, but the developers didn't pay much heed to the look of the comics, for good or ill.
I doubt Kun used it in his lightsaber, since it was "put together" by Tam, though I suppose it could just be a bastardised version of a previous lightsaber crystal that Kun used.

I think its good to put a ligthsaber image with the crystal equiped, to have a better view of its color. viento 18:50, March - 8 -2007
I put this image on the page several weeks ago, but somone called Chack Jadson took it down; said Revan's appearance was unconfirmed. When I posted the picture I included a caption that said it was one of Revan's possible portraits, but he still took it down. --Ninsegtari 05:05, 5 December 2007 (UTC)
So does anyone know if you can use the Mantle of the Force and the Heart of the Guardian in the same lightsaber? It just kind of confuses me is all.
