The Cybernetics Core is where the necessary materials for the construction of a Dragoon walker are kept. This is also the site of "essence translators". Though it is debatable about what these things truly are, my theory is that they help the fallen Protoss warrior focus their spirits through the Dragoon, effectivley making it an extension of their body; their very soul permeates the dragoon itself. Still, even though theese things contain their spirits, the warrior's orignal body is kept within the core of the dragoon, for it still serves as an anchor for the spirit in the material realm of reality.
