[The Might]

Aha!

I think I have it... you truly are tricky with your questions, but I enjoy them I must admit.

Ok, so my answer is the the Master of Lake Town.

The old Master had come to a bad end. Bard had given him much gold for the help of the Lake-people, but being of the kind that easily catches such disease he fell under the dragon-sickness, and took most of the gold and fled with it, and died of starvation in the Waste, deserted by his companions. ~ TH

1. There was a person.
2. This person was vulnerable to a certain kind of disease.
3. This disease is a kind you won't usually find in a medic's handbook.
4. It caused this person, eventually, to move far from this person's home place.
5. That person did not die because of the disease, as far as we know.

It fits with all, as he did get the disease, it is in no medic's handbook, it caused him to go to the Northern Wastes and nothing was heard of him afterwards. Although he did die of starvation, it was not the disease which caused it. And since it is said he was "of the kind" he did belong to people having this by default.

If this is wrong too, I'll first buy me a hat, then eat it.
