I am actually living an adventure with some friends, in a magic world, already built. There are anatomical knowledge to a certain level (let's say we may be able to find some books and papers on advanced anatomy at a certain point in time), and we are using real-life diseases like fungal poisonning, etc.
One of the character has a mysterious disease called "hematophagocy". Basically, his own blood is devouring his body. We found out by searching that the core of the problem resides in the bone marrow, producing the blood. So we want to cure it !
How would you do it magically ? Because I do not think you could replace the bone marrow entirely with existing techniques (does such techniques exist ?). I am searching for something somewhat plausible, like:
- Rituals
- Brewages
- Chirurgical magic-helped operations
- Means to prevent the disease from growing
- Etc ...
Thank you in advance !
EDIT 1
I asked the question here for two main reasons: one, because the frame of application of this question is really, really wide and permissive. And second, because it is online, so there are not that much of a GM / DM there. I would say, in this context, that the one which will be able to validate will be the one who created the disease (and has it on his character).
EDIT 2
As suggested in the comments, I shall add some bounds. A solution will be evaluated as "plausible" based on accuracy of the measure (ex: "Snapping fingers" VS "Snapping fingers after rassembling blood from a gnome and then boiling it into a potion"), sources (your imagination if ever, or when do you find the information about whatever magic / cure you propose), and bonus points on background accuracy (if you know the background of Wakfu MMO only).
