The concepts behind Shadowtech are truly baffling even to mad scientists like us, Cap'n. Apparently the Shadowmasters put a great value in human emotions, and somehow use them to manifest improbable feats of technology, fully intertwined with magic. Our Codex is a proof of this; it alludes to an arcanist system, which describes the full spectrum of human emotions on a circumference of a star. Anger, Focus, Joy and Acceptance are the 4 positive emotions that flow into each other in that order; followed by their mirroring negatives of Fear, Confusion, Sadness and Disgust, and back to Anger again. Each Codex represents one +/- pair. The next concept is the opposition of Codexes; Red (Anger/Fear) is located opposite to Gold (Joy/Sadness), and Gray (Focus/Confusion) opposite to Green (Acceptance/Disgust).
