One of the Guilds of D'ni. They began to fear that the plague released against the Pento could mutate to something else. When Ahlsendar's Plague turned against the D'ni, the Guild of Healers and the Chemists were working hard to find a cure. King Behnashiren was of no help and in some of his speeches he accuses the Guilds of "shallow efforts" and "failing their own people." Notable Chemists were the unfortunate son of King Yableshan, and the father of Hisha.
