A young boy, about 15, wanders into your village, singing a song with no lyrics. He's dressed for travelling, the soles of his boots are worn through, and there is dirt on many parts of his body. He has ropes around his wrists that have been frayed in places, suggesting he has broken away from some tether. You decide to approach him, and finding that he speaks the Saxon tongue, you take him to your abode to clean him up. As you do, you find a strange set of markings on his torso, the skin around them tinged green. The bite of a baby dragon. What is wrong? He asks you.
