This quest is available from Xanthor, Catherine Ironfist's court wizard, who is visiting Jadame due to the crisis. He is staying in the Hostel facing the crystal.
Once you have completed the quest to Sink the Regnan Fleet, Catherine Ironfist and her court wizard, Xanthor will be able to land in Ravenshore. They have been invited to help solve the problem. Fellmoon will ask the party to report to Xanthor, who will know what needs to be done. He (Xanthor) will ask you to locate and bring back the elemental hearts, which are pure substances of the four elements in crystal form, and which can only be found on their respective planes. These are necessary so he can make a key to Escaton's Crystal, the pink crystal in the Ravenshore town square. The key must resonate with the four elements, which is why he needs the hearts.
Walkthrough[]
This quest is broken up into four sections, each representing a single elemental heart. You will receive a portion of the experience points each time you return from an elemental plane with the heart in your inventory. Xanthor, however, will not recognize that you have done anything or take the hearts from you until you have acquired all four of them (despite the wording in your quest log, which implies that you must return to Xanthor after acquiring each heart, this is considered a single quest with a single return to Xanthor at the end). Below are links to the walkthrough portion for each elemental heart.
Bring the Heart of Fire from the Plane of Fire to Xanthor.
Bring the Heart of Air from the Plane of Air to Xanthor.
Bring the Heart of Water from the Plane of Water to Xanthor.
Bring the Heart of Earth from the Plane of Earth to Xanthor.
The quests may be completed in any order.
