The Night elf that you see in the video,is a moon priestess.She's searching his lost sister Velinde Starsong.The carrier of the scythe of elune,Velinde in the real lore doesn't have a known sister.And it doesn't say anything about his family,so is not difficult to create a background history about his Sister(the priest in the video).I hope you like it.
