Hezle

The leader of the mining operation is one of them—a kobold named Hezle, whom the kobolds insist is “not bad like the others.”
Because the players helped the Runaway Kobold Miners they tell the PCs the “secret name” of their original tribe (the Thornscales), and mention that if they speak this tribe name to Hezle at the Cinderclaw mine as proof that the players helped her kin, she might help them in return.
