Tips, tricks & notes:

• There are a number of speedy ways to travel back to Rellekka throughout the quest. Having your house located at the Rellekka portal will allow you to use Teleport to House to return quickly. Alternatively, you may use Enchanted Lyres to teleport directly into the city.
• If you speak to Baba Yaga on Lunar Isle while holding the unfinished astral rune, she will fill in the rest of the story. After telling her story, she will reward you with the real prophecy tablet and an antique lamp worth 2,500 Experience in any skill. You may take the prophecy tablet to Historian Minas in the Varrock Museum to receive 10 kudos.
• The Tome of Glorious Deeds will give 3 times 5000 Experience to any one of these skills, provided they are over level 40: Attack, Strength, Defence, Constitution or Ranged.
