At age 20 Greft is the eldest of the Dragon Keepers. He decides that he should be the leader of the group and assumes this position. Some of the Dragon Keepers accept this, but some, like Thymara, Tats and Sylve do not.
Greft is the keeper of Kalo, but is rejected by Kalo after Greft's requests for blood to change him into an elderling and to sell to the Duke of Chalced for money. He is the mate of Jerd, and wanted to make a new city run by the keepers in Kelsingra. Unfortunately, this never happened, because Greft became sick, and he left in a canoe and was poisoned with gallator venom and was found in his canoe by Carson Lupskip and died shortly after.
