Find a brick behind a force cage in lower Attilan.
Follow a clue out front to unearth a teleporter by a different cage.
Blip through to find yourself in a cage with a pressure plate and a hulk-handled chest.
Stand on the plate to dismiss the force cage, and tear open the chest for the pieces to yet another teleporter.
This takes you to a different cage, again with a pressure plate, but also with a clue to follow.
The teleporter at the end of *that* trail is the one that will finally blip you over to the brick.
