Enju is the elder of the Dawnstar siblings and takes his role as big brother very seriously. Enju and Enmai's parents were a former ranger of Silvermoon (father) and mage (mother), who retired from their former careers and became merchants. They ran a successful company until their accident at sea which took both parents' lives and left Enmai emotionally scarred.
Enju who was studying at Dalaran rushed home to collect his sister and take her to Dalaran to study and so he could keep an eye on her. Things didn't work out and she was sent to Silvermoon a few (months? years?)later. After the fall of Quel'Thalas, Enju returned home to find his sister once again but this time he would not return to Dalaran.
The magical addiction has hit him hard. Enju always had a harder time dealing with it than other Blood Elves, his attempts to curb the urge to mana tap usually leaves him feeling listless and constantly fatigued. Although he works hard to prove his worth to his new allies, Enju has frequently taken long sabbaticals to rejuvenate from over work and stress.
Enju's one wish is to rebuild Silvermoon and heal the desecrated scar of land in Quel'Thalas. He does not have any interest in abandoning Azeroth for Outland so he distrusts the words of the Grand Magister. Rather than speak openly against the current administration, he seeks to gain access to Outland and see the land that his Prince has abandoned his homeland for with his own eyes.
