Mechanized-crystallin humanoid robots! 
Shiri, you wanting golems so much makes me think you were a druid somewhere... *peer*
So, in history it says how gems are essential for the matrix, then you could consider gems/crystals as fuel... make an mechanic exterior embed it with crystals all throught the steel exoskeleton. Place a core from a substance found in the Continuum, use magicks to energyze the core and the core sending the energy to surge accross the body channeling with the crystals... giving you your own... G.O.L.E.M robot!
(now I just need to find out for what the acronym of G.O.L.E.M could stand for... Guardian.Ohm.Liberated.Eletricaly.Mechanized Robot, suggestions? I'm just adding words)
Edit: Further development. The "core" inside the golems could be the amorpheus oozes I mentioned earlier, the ents of the continuum in the hand of the Institute of the Matrix, that in the prime plane, because they are rather unstable and constantly keep changing shape, the Hallifaxers decided to make G.O.L.E.M robots using the oozes as core energy. This stabilizing the oozes to a very good point, allowing it to channel it's energy throughout the G.O.L.E.M, thanks to the aid of crystals layed around the steel mechanism... giving it movement and the Guardian powers the members of the Institute of the Matrix need.

Okay, if that weren't such a bad acronym, I'd like it. And I was a druid somewhere, but I didn't like it in Groves, I want proper golems, not dodgy earth ones!
Now all we need are the two lost cities and all will be set!
