Simon took in a deep breath, only to let it out with a heavy sigh, running a hand over his mouth. "They're limited," he said vaguely. "There's more than you'd think. We've been able to treat traumatic injuries and I just did an amputation without feeling like I had to give her something to bite down on while I took a hacksaw to her arm. But in terms of illness..."
He frowned. "We don't have anything to treat something like this. Not off-hand, and in terms of creating something new, that's even harder."
