Jorium is a rare crystal with unique properties. It is yellow in color.[1]
Overview
Edit
Jorium can be safely handled without protection.[1] It resonates at the same frequencies as some brain waves, and may be used to stimulate brain activity and produce psionic abilities in terrans.[2][3] It also stabilizes terrazine, another psi-enhancing substance, and minimizes its hallucinations and side effects.[4] It is required to create spectres.[5]

A crate of jorium
Jorium is also used for military and scientific applications, and as such sells for a high price on the terran black market.[6] Abathur found jorium useful for experimentation, as it enhanced the psionic potential of the zerg.[7]
Jorium can also interfere with telepathic abilities.[1]
History
Edit
The Terran Dominion used jorium to enhance ghost powers during Project: Shadowblade,[8] and when the Spectre Rebellion occurred the rebel spectres utilized it as a stabilizing agent. Colonel Jackson Hauler monitored his jorium intake to the minute to prevent the insanity from terrazine use. However, many of his followers neglected to take the jorium treatments.[4]
In 2504, a Dominion jorium freighter was hijacked by pirates.[9]

On Redstone III, Raynor's Raiders helped Gabriel Tosh mine minerals[10] which contained trace quantities of jorium, although Commander Jim Raynor was unaware of this until it was found by Doctor Ariel Hanson.[2][3]
Tosh's Goons set up a jorium stockpile on Avernus Station so as to build a spectre army. It was destroyed by Nova with help from Raynor's Raiders.[5]
A Dominion transport containing jorium crashed on Brokas Hur.[7]
The zerg used vipers and aberrations to secure jorium from the wreckage.[7]

Elms holding jorium
After the End War, jorium came in big demand for the Terran Dominion, and fetched a high price on the black market. A force under Captain Hogarth violated the Dominion/Daelaam DMZ in order to try to steal crates from the planet Adena to sell for themselves. However, they came under attack from the zerg led by rogue Broodmother Niadra.[6] A team of scavengers, including a telepath named Elms, managed to save a few marines and escape with the jorium.[11] After evading Dominion forces, Elms brought the jorium to the Last Junction to sell to James Sykes. However, Sykes attempted to betray her and steal the jorium for himself, resulting in a shootout between Elms' scavengers and Sykes' mercenaries. After subduing Sykes, Elms realized that the jorium was adversely affecting her telepathic abilities, as she hadn't been able to detect Sykes' true intentions until it was too late.[1]
