Tanen Gard is an ancient dragon burial ground and the location of the hidden Crown of Horns. Only Dragons are permitted in Tanen Gard and if a creature besides a Dragon enters then the penalty is death. Only very few non-Dragons have entered and lived. Thorn Harvestar and Fone Bone have both entered twice and lived. Smiley Bone, Phoney Bone, Rose Harvestar, and a many named and unamed rat creatures such as Bartleby and Kingdok have survived trips into the burial grounds. Tanen Gard is also the final resting place of the Queen Dragon Mim, whose body was taken by the dragons into Tanen Gard after the Lord of the Locust was killed and stopped possessing her body.
