Jaleesa is a green Dragon with emerald scales and a pair of fins just behind her head fans out and retracts. The Dragon is nearly as immense as Celebrant and she captured Kendra and brought her to Celebrant, the Dragon King. Jaleesa then probably proceeded to chase Seth and Eve when they were flying for Blackwell Keep on Tempest. She forced them to take refuge at Terrabelle instead.
Jaleesa lost her arm while in human form when she violated the rules of the competition at Stormguard Castle.
