The Apothecary

The fungus of a twisted tree that appeared deep in the forest of Zha'at-Dlje is exclusively infecting small dragons, but the Apothecary knows that it is only a matter of time before the tree mutates and infects bigger creatures so, much to his regret, he dissected an infected dragon to study the fungus and find a way to coexist with it if it's possible, if not, he'll destroy it along with the tree.
