Erasmus had a skin of organic-plastic composites laced with neurelectronics. He pretended that the sophisticated sensor network allowed him to genuinely feel physical sensations. Under the glowing ember of Corrin's huge sun, he detected light and warmth on his skin, presumably like real flesh. He wore a thick gold robe trimmed in carmine, part of a stylish personal wardrobe that separated him from Omnius's lesser robots. Vanity was another thing Erasmus had learned from studying humans, and he rather enjoyed it.
