Meltmassif

Meltmassif was a substance that was predominant in the caverns of Cronal's base on Mindor. It was used in the construction of the Shadow Throne, Shadow Egg, and the shadow stormtrooper's armor. The crystals themselves were implanted into the brains of unwilling participants known as Pawns and the task of doing so occurred at the Pawning Table. It could melt on contact with an external object, and in some cases an organic being.

Mineral based sentient beings known as Melters used the meltmassif as their medium and communicated between it. They could materialize out of the very walls that formed the caverns. The Melters would then take any organic intruders and deposit them into the meltmassif. It appears that the deposition of a being into the meltmassif allowed them to harness that being's energy output.

R2-D2 found that it was coursing with electromagnetism.
