Everyone gets ready, setting themselves up to move on the signal, preparing to orchestrate a single, highly interconnected action. Their parts are all known, their interactions studied, their purpose clear. Open door, pull Alex free, push the bomb in, close the door, run. They've talked it out and practiced, there is nothing left but to do it.
Ashul, who has to be closest when it all happens, positions himself next to the door, but ready to run. With after a few moments prep, running through the motions once more in his head, he activates the door. He runs as it opens, hitting the switch on the bomb as he passes and continuing on at a lopsided gallop on deformed legs. The door opens in its strange, deflating way, and as the fleshy membrane slides and reveals the bright interior, Adam and Clate go to work. Adam activates a dive as soon as he has eyes on Alex and yanks the man clear of the cist, teleporting him into the coffin with a dull thump of air rebounding into the space he used to occupy. Then Clate pushes the bomb in. He gets... a bit overzealous and the bomb ends up being tossed in as though from a catapult, tumbling towards the warrior. The warrior, seemingly expecting such a thing, catches it with one hand, sliding back a foot or two from the force. And then The door is already closing, Ashul gesturing for it to do so as he dives into cover.
And then there is a long pause as everyone hunkers down and covers their ears, uncertain what to expect. Will there be any noise? Any rumble or shaking? Will the door blow open? Will the tunnel collapse? Many have their eyes closed, while Nyw keeps steady watch on the image reflected in his knife. How many seconds has it been? 5? 10? They count to themselves. When everyone's count passes 30, they open their eyes and look at the door. It is unchanged. They look to each other and then back at the door. Has it gone off? They didn't feel anything, physical or mental. They believed they would feel the mental shockwave at least.
Everyone is silent, watching the door. A minute passes. Nothing changes.
