This is my third try to send word back. The other boatmen refuse to go to your island any more. Let me know if this letter arrives unopened. Not so sure about this new lady.
I wish I had better news. But your assessment of the patient is correct. After digging through the university's archives even in the old world there weren't any solutions to the specified problem. Nothing even remotely approaching clinical trials. I doubt our mutual friend has any better news. Again, regrets.
Is everything OK over there? We keep seeing islanders coming through. They tell disturbing stories. If you EVER seek to leave, my friends and I would eagerly welcome you if things get too bad, either leave or send word.
