Illusion

The Aon was extensive and complex. Raoden had to take several steps to the side as he drew it, the modifications and stipulations going far beyond the central Aon. His arm ached by the time he had finished, and the construction hung in the air like a wall of glowing lines. Then, it began to gleam, and the sheet of inscriptions twisted, turning and wrapping around Raoden. Galladon yelped in surprise at the suddenly bright light. In a few seconds, the light vanished. Raoden could tell from the startled look on Galladon's face that he had been successful. 'Sule .. . you've done it! You've healed yourself!' 'I'm afraid not,' Raoden said with a shake of his head. 'It's only an illusion. Look.' He held up his hands, which were still gray and spotted with black. His face, however, was different. He walked over. regarding his reflection in a polished plaque on the end of a bookshelf. The garbled image showed an unfamiliar face, it was free from spots, true, but it didn't look anything like his real face had before the Shaod had taken him. 'An illusion?' Galladon asked. Raoden nodded. 'It's based on Aon Shao, but there are so many things mixed in that the base Aon is almost irrelevant.' 'But it shouldn't work on you.' Galladon said. 'I thought we decided the Aons couldn't target Elantrians.' 'It doesn't,' Raoden said, turning. 'It targets my shirt. The illusion is like an article of clothing, it only covers up my skin; it doesn't change anything.'
