I can't take the quest for reputation of knights of the ebony sword

Hello, how are you, a few days ago I reached 80 with my warlock, it is my first character in Lordaeron but I already have 20 years of experience in wow, it is assumed that an npc in the Dalaran flight zone will give me a mission that will send me to look for someone in a zepeling, and there I will start farming reputation for knight of the ebony sword but the NPC in Dalaran does not give me any mission, please help me my walock's name is Kaioma
