Head over to White Wolf Mountain east of Catherby or west of Taverley. Speak to Ejjar, and he will ask you to retrieve him a coil of rope, a potato with cheese, any hatchet and either a normal cake or a chocolate Cake. Give him the items and he will start telling you about the Dragon Defender. After you have killed all the cyclopes, Ejjar will appear and he will start attacking you. He is fairly easy to beat if you have 43 Prayer and pray melee. After you defeat Ejjar, you will appear then to the guild members in the storage room. Congratulations, Quest complete!
