The Maps of Myrist
A large, open lava crater in the Lavastorm Mountains, known as Solusek's Eye, is the lair of many dangerous and rare creatures. The worst of these is the obsessively greedy ancient red dragon, Nagafen, who was cast out of the Ring of Scale for reasons known only unto himself and the elders of the great council.
Carved by fire goblins centuries past, the subterranean complex of Nagafen's Lair is a veritable maze of winding paths and thin, narrow bridges of stone that hover uncomfortably above rivers of flowing magma. Many chambers in the topmost region of the lair are inhabited by the kobolds loyal to Lord Nagafen. Although subdued beneath the tyrannical dragon's will, the kobolds have managed to uphold their own traditions and culture – proudly sustaining their own king, nobles, and high priests who order everyday kobold life.
