Kai Akua. Guardian of Seas and Ferryer of Lost Souls. I'm not quite privy to what's happening with your friend but I can read commentary and put the pieces together that it doesn't look very good. I remember the first critical outbreak of Yellow Fever. Highly unpleasant. I'm sorry your friend has to suffer through this. I wish there was more I could personally do. That said, surely there is enough power among us all to help him! Have faith.
