Doctor Kreiss has done all he could for Corwin. He explains to you the situation. He's lost so much blood under a short amount of time. To compound difficulties, he's suffering from a very rare blood disease called Nagi Syndrome. It makes finding a donor incredibly difficult, in the best of situations. But this isn't one of those situations. The doctors explain all this to you. He doesn't seem to have any of the biological markers that someone who is suffering from this disease should have. Someone customized this blood disease intentionally to hurt him. He continues explaining the situation, after taking a deep breath. Corwin is in critical and unstable condition right now. He is only alive because you helped bring him here so quickly. Corwin only has one chance to live, and they do not know what will happen. He cannot replace the blood Corwin lost. But it may be possible to stimulate his bone marrow into producing additional blood. They have never done anything this risky before. The results are unknowable. He asks you. Do you want him to try?
