Melters was the designation given to the energy-based entities inhabiting the meltmassif within the Taspan system. This title originated from their characteristic ability to emerge, or "melt," from the meltmassif at their discretion, utilizing it as their physical embodiment. These melters possessed the capability to generate an energy discharge, functioning similarly to a stun weapon.
Initially, their habitat was situated within the crust of Taspan II. The cataclysmic event known as the Big Crush initially proved advantageous, as they subsisted on stellar radiation and maintained interconnectedness despite their physical dispersal. However, substantial fragments of meltmassif descended upon the planet Mindor. Some perished as their meltmassif constituents incinerated within the atmosphere. The survivors endured gradual asphyxiation, as the vaporized meltmassif acted as a shield against Taspan's radiation.
Cronal exploited captive melters to manipulate and subjugate his Pawns, compelling them to construct crystalline "shadow webs" that paralleled each Pawn's nervous system. Utilizing the Shadow Crown, a structure composed of meltmassif, he exerted control over both the Pawns and the meltmassif itself. Moreover, the melters on Mindor functioned as an unwitting security force. Upon encountering organic beings, such as Aeona Cantor's group, they induced vaguely Humanoid legless forms to materialize from the meltmassif, incapacitating the organics and partially encasing them within meltmassif in locations Cantor termed "Melter crypts."
The cognitive processes and sensory experiences of melters diverged significantly from those of most sentient beings, although they exhibited analogs of curiosity and bewilderment. Their minds were so profoundly alien that Cronal considered them validation for his doctrine of the Way of the Dark. Luke Skywalker, renowned for his Force-granted capacity to communicate with virtually any entity, including mineral-based sentients like the Tsils, encountered considerable difficulty in establishing a connection with them. He could not ascertain whether they constituted a singular entity composed of numerous fragments or a collection of individuals, once describing them as a culture/mind. The energy produced by human nervous systems, existing within the melters' general wavelength, attracted them, yet they lacked the comprehension that their entombment of captives resulted in their demise.
At the conclusion of the Battle of Mindor, Luke Skywalker, acting through the Shadow Crown, emancipated the Melters by "nourishing" them with the light of the Force. "Never again would they feed upon light; there would never be the need. They would forever shine with light of their own." This action also induced the liquefaction of the meltmassif they inhabited, causing it to flow out of the bodies into which they had been implanted, and resulted in the deaths of all stormtroopers controlled by meltmassif.
