Speak to the Wise Old Man in Draynor Village, and he will ask you to do him a job. He wants you to obtain the Scroll of Zaros, and if you do so he shall give you a reward. Accept and he will give you a translation map and ask you to speak to Zimberfizz about translations. You now need to go to Soul Wars (must have started Nomad's Requiem for this bit) and ask him for translations. He will now give you the translations on another scroll for 2,000 coins.
