Took a little doodle that I did while rewatching Karas on DVD (very, very cool anime, by the way). Armor like this has to be magically summoned, since it takes a lot of time and assistance to put it on or take it off normally. What it's actual capabilities are is somewhat up to your imagination, but I figure a couple elements are universally necessary, and they're noted above.
"codex" is just a fancy-soundin' word for "manuscript". The text here is the John Handy font in Photoshop, and the whole texture is a couple of hi-res scans of actual paper that is blended with the line art and text.... pretty easy stuff, I hardly feel like I ought to take any credit for it at all. Just playing about with the lines.
It could happen. Most of the armor designs on my mind these days are for Shardplate (for Sanderson's "Stormlight Archive" series), which share some of the same aspects.
a very interesting design, reminiscent of the greenwhich armour style perfected for henry VIII of england, the first fully articulated and completely encasing armour, the sidenotes are exceptionally thorough, an amazing artwork and fantastic codex
Thanks! Greenwich armor still has to deal with all the real-world restrictions of movement and materials, which is why it leaves open space at the groin and behind the legs. But the nice thing about fantasy is that you can separate yourself (to some degree) from realism.
