The high templar, charged with wielding the psionic powers of their race, used the archives to access memories and strands of experience from the Khala and thereby gain knowledge inaccessible to ordinary warriors.
With the corruption of the Khala during the End War, the archives fell silent, the memories of the Khalai's ancestors lost to them.
Tal'darim utilize a variant of the templar archives in order for high ranking ascendants to relive their most heroic deeds. The Ihan-rii meanwhile use a variant of the templar archives that hold their race's closely guarded secrets, including the process to produce their semi-organic animated stone.
The high templar selects a unit, creating two duplicates of it. Hallucinations appear with a blue tint to the creating and controlling player, while all other players will see them as duplicates of the original. Hallucinations do not inflict damage when they "attack", may not cast spells, or produce units (important for hallucinated carriers and reavers), and take double damage from all attacks. Hallucinations last for a limited time and automatically disappear when hit by spells (eg. EMP shockwave, Mind Control).
Prevents allbiological units (friendly included) within a 4 x 4 area from attacking, moving, or casting spells for short period of time. Stunned cloaked units will be revealed. Burrowed units will not be revealed or stunned.
Transfers control of any enemy unit to the casting player. Using Mind Control will drain the dark archon's shields and leave it vulnerable.
Mind controlling a transport will also transfer control of any units the transport is carrying, and mind controlling a unit that has researched upgrades or special abilities will transfer them to the dark archon's player.
The transfer is permanent and irreversible, even after the death or the transfer of control of the dark archon who performed it. Any unit can be subject to multiple Mind Control spells, effectively changing ownership every time.
Psionic Storm deals 80 damage in the target area in small packets over 2.85 seconds, and hits both air and ground units. It injures friendly units caught in the area of effect of 1.5.
Psionic storm is smartcast.
Psionic Storm is subject to a short delay before striking; during this brief period there is a visual indicator for where it will strike.
The templar archives is available to Artanis and Alarak, though the latter's is named "ascendant archives" and has a different skin. Artanis's archives allows the training of, and houses upgrades for, high templar, while Alarak's does the same for his ascendants.
