Phlegnn

Plague Dragon of Sloth

Phlegnn is a plague dragon who refuses to leave the hot spring that supplies a village’s drinking water. He says he needs the steam for his illness, dismissing the villagers’ sickness as their problem. Lim’s treatment hurts him and briefly turns him golden and energetic. Galanoth says his diseased form is his natural state. Further treatment and a fight end in Phlegnn’s destruction.
