A dimensional stabilizer..? [It's not that he doesn't have an explanation, but rather that he needs a moment to make sure it makes sense.]
Well, you already know that the people in this prison come from many different worlds. Different dimensions. It's unlikely that those dimensions work under the same laws of nature — for instance, our intake of oxygen is considered natural where we're from, but in another dimension that could be lethal. A dimensional stabilizer would neutralize all those needs so that we can all co-exist in the same environment.
At least, that's the basics of it... there is something else. [Normally this is where he'd say something about talking about it later, but he can't be bothered with playing it safe right now. Chances are the Wardens are listening at all times.]
I'm not sure, but... back during the coup, Acumen altered our physical condition in an attempt to slow down the attack. Breathing difficulties, flu-like symptoms, vertigo... add to that the bodies of everyone who's gone missing here, and the fact that anyone who wasn't going underground with Sentience was found in a similar state. Sleeping, impossible to wake up.
