Good job! I like it. But I have a question. Two in fact. :) I understand how a pressure suit functions. That is, they maintain an atmospheric pressure within that is compatible with the human respiratory system and therefore I can only assume the Cabal pressure suit must be similar. Simply put: when a human being inhales the muscular diaphragm moves downward, thus allowing room for the lungs to expand as atmospheric pressure rushes in to fill the vacuum created by doing so. We call that inhaling and it's a autonomic response, although when conscious we have some control over it. For instance, we can hold our breath if we want. But eventually we'll take a breath as we have no control over it at the point. The autonomic nervous system simply overrides our willpower and is what keeps us breathing while we're asleep. That said, atmospheric pressure, be it greater or lesser than sea-level, is a factor. For example, at very high altitudes or in the depths of an ocean, there are significant factors that must be taken into account. For instance, at very high altitudes a pressure suit or pressurized cabin is required, as is the case in outer space. Whereas when underwater, as the depth increases, breathable air, which contains Oxygen and Nitrogen, becomes toxic at great depths and thus one must breathe a mixture of Oxygen. Nitrogen and Helium. Not something I've ever needed to do, although I did attend (and graduated) the Army's combat diver qualification course at one time. So, question #1: Although they wear space suits (includes a worn helmet), do Guardians need to breathe? As to question #2: Could you explain how a Cabal pressure suit regulates a [u]gravitational field[/u] effect on a Cabal soldier? For example, Jupiter's moon Io is about the same size as Earth's moon and thus its gravity would be roughly the same, or about 1/6 of the gravity a Guardian feels on Earth. The force of gravity on an object (a mass) is expressed as its 'weight'. Hence, a Cabal soldier on Io would weigh significantly less than they would on Earth. As would a human being on Io. And on Jupiter itself a human being would weigh approximately 2 1/2 times what they do on Earth. (I looked it up and I'm surprised it's not more). So one must presume the Cabal would weight 2 1/2 times what they do on Earth as well, as would an elephant for example. But how does their pressure suit compensate for that? Inquiring minds...
