Protoss units and buildings!

All Information collected from the official Starcraft 2 website!

Units:

Zealot:
For over a thousand years the Templar caste of the protoss have defended their people from threats both internal and external, dedicating their long lives to the pursuit of martial perfection. Zealots are peerless templar warriors who have yet to achieve the uppermost ranks of the Khala. Ever eager for battle, zealots train constantly to attune themselves more closely to the Khala's disciplines and prove themselves worthy of advancement. They exemplify the unbridled ferocity of the protoss at war.

Immortal:
Before the loss of Aiur, veteran protoss warriors who had been crippled in battle could volunteer to continue their service by being transplanted into dragoon exoskeletons. Now the dragoons of the past are all but gone. The sacred shrine that was dedicated to the creation of the dragoons was infested by the zerg and lost along with the protoss homeworld itself.

Stalker:
The dark templer are a branch of the protoss race that refused to surrender their individuality to the encompassing psionic gestalt of the Khala. In ages past they were exiled from the protoss homeworld of Aiur. They eventually found a new home on the distant planet Shakuras.

Phase Prism:
For thousands of years the protoss have studied the nature of time and space. Through their painstaking studies and experiments protoss researchers have uncovered many of the secrets of the universe. Using psionic manufacturing processes, the protoss have learned how to create a robotic mind whose programming is built into the molecules of an advanced crystal lattice. This "crystal computer" is able to manipulate matter and energy with a precision no ordinary organic mind could comprehend.

Building:

Gateway/Warpgate:
the protoss' ability to manipulate time and space far surpasses the limited understanding of other races. A gateway is a structure capable of opening a spatial rift via which protoss forces can be warped directly from their home territories to the battlefield. A phenomenal amount of energy is required for this operation so, as with all protoss structures, a gateway can only function if it is powered by the psionic matrix formed by a network of pylons or phase prisms.
