The Elder Elemental opened one diamond eye, staring out at the world it had been imprisoned in with a look of singular hate.  The creature vibrated slowly but surely, straining against its bonds as it realized what was happening.  The air around the engine room filled with expectation, while the vicious creature began to explode the tiny pins and diagrams that kept it from moving.  The players made their moves, and the creature answered, a mouth like a forboding cave opening and roaring like an angry volcano.  "NO MORTAL MAY CONTAIN ME!  NO CREATURE MAY CONTROL ME!"  The Elder shouted in Terran, sounding to those unfamiliar with the language like a falling avalanche.<br/><br/>With a final lurch, the Elder smashed open a hole in the side of the machine, making the entire thing crack and buckle, as the defensive wards that had kept it intact all began to fail.  The gigantic monster contained inside pushed its way to the side of the machine, pulling at the sides of the hole it had made, hoping to make just enough room to escape.  The Elemental was obviously going to tear the machine in half to get out, possibly dooming everyone inside.  In the tomb of earth the group found themselves in, it was going to take more than a bit of cleverness to escape.<br/><br/>(I'm willing to allow an improvised ritual, if that's how you guys would like to get out.  There's about 50 feet of dirt between you and relative safety.)
