Disturbance in the Ley Lines

Quest Overview
Investigate possible ley line disruptions caused by Lord Rytheran at the behest of one of two factions for Major Life Magic, Major Magic Resist Headpiece. Very important lore developments for the observant.

This is a popular quest due to its short repeat timer and being quick to complete. You can either kill Rytheran to take his mnemosyne and visage (plus a few other rewards in the chest), or retrieve his ring and return it to him for the same items. Second option is strongly advised if you are doing this quest solo.

Walkthrough

 * 1) Speak to either Lacarra Avanthi at 61.8S 51.3W or Zho Heishan at 61.9S 51.4W, both in Wai Jhou. Lacarra is associated with the Radiant Blood and Zho is associated with the Celestial Hand. Pick the one depending on which faction you are sympathetic to (the town crier indicated there are only a pair, and from the lore found during the quest it appears the Eldrytch Web and Rytheran, as a leader of some sort in that faction, actually is part of the disturbance).
 * 2) * Warning - Once you talk to either NPC, you cannot engage the other NPC for the quest.
 * 3) Travel to Graveyard and enter the Gardens of Menilesh at 64.7S 43.8W.
 * 4) Speak to Lord Rytheran at the start, he will instruct you to retrieve a ring. You have a choice at this point, you can continue down and get the ring, or you can kill Rytheran. There is no known differences between these two options, however Zho Heishan seems to imply you can do this without killing him while Lacarra suggests killing him (see lore below). Caution he is much tougher now, so i don't suggest trying him solo except if you are a mage and good at slide casting, Do not try to vuln or imperil him, he will counter-buff. He doesn't regen but will probably reset if you die and nobody else is in the dungeon (so being dual-logged with a healer at the entrance of the corridor is strongly advised ). Once he is dead, he drops 9 Engraved Ashen Keys on his corpse to be used on one of the 2 Lord of Menilesh's Engraved Chests nearby (so get 8 other toons first inside the dungeon if you are soloing this ). The chest contains the Visage of Menilesh, the Rytheran's Mnemosyne, an Ornate Bone Key, a mhoire coin, four level 8 comps and 2 random high tier loot pieces. Lord Rytheran does take a good amount of time to respawn (about 8-10 minutes).
 * 5) * Note: The items in the chest and the ones that Rytheran hands you are on the same timer, so if you want double xp on this, you have to hand him the ring AFTER looting the chest. if you do it the other way, it won't work.
 * 6) If you kill him, skip the steps 5-7, if not continue on in the dungeon.
 * 7) Not far from the start is a Strange Pillar. When used it summons many moarsmen and undead. This pillar servers a role in another quest, Jester Focuses.
 * 8) The dungeon forms a large circle, so you can go left or right and both lead to a large room in the middle with the Ring of Remembrance on the floor. From the drop, go down several levels, coming to a room with the Strange Pillar in the middle. Go west, up the ramp and south, stick left and you'll come to a large room with the ring on the floor in the middle. The ring respawns quickly and has a 13 day pickup timer.
 * 9) Return to Lord Rytheran at the start and give him the ring, he will give you the Visage of Menilesh and Rytheran's Mnemosyne.
 * 10) Go back to Wai Jhou and give the Mnemosyne to the NPC you originally talked to for the experience reward. If you don't want to Visage of Menilesh you can give it to the NPC for 5% xp.

Note: The choice you make in which NPC to use here has no long term impact when joining a faction. Note number 2 : There is one difference between killing Lord R and giving him the ring; If you kill Lord R you get to loot his chest and in the chest is an Ornate Bone Key. The key is used to summon a portal to start Lord M.

Lore & Dialog
If you are too low level:

Zho Heishan tells you, "I don't believe you can help me. I seek a stronger champion to face great peril." Lacarra Avanthi tells you, "You are too weak to help me, youngster. Seek me out when you have become stronger."

Zho Heishan tells you, "Excellent, perhaps you can help me. My superiors seek some knowledge of the troubles affecting the ley lines of Dereth, and the problem seems to trace back to Rytheran, the ancient Dericostian noble.  We have become aware that a path into Rytheran's current abode within the ruined Gardens of Menilesh has opened somewhere in the Empyrean Graveyard." Zho Heishan tells you, "Find a way to seek out Rytheran and see if you can retrieve his personal mnemosyne... We need access to his memories about the reading of the Book of Eibhil. It may not be necessary to destroy the undead lord, but merely to attain his cooperation."

OR

Lacarra Avanthi tells you, "You may be worth my time... My masters have determined that the dusty, deposed Lord Rytheran is the source of our current troubles with ley lines. If you would make yourself useful to us and to all the humans of Dereth, seek him out in his garden sanctuary." Lacarra Avanthi tells you, "There is a portal to these gardens located in the midst of the Empyrean Graveyard. We need a mnemosyne from Rytheran, bearing... vital information about a book he once held.  Take it from him, by force or coercion, and bring it to me.  You will be well rewarded."

Lord Rytheran tells you, "Ah, you seek my mnemosyne, do you not? My memories of that long-ago day when I read from the book... Your masters desire it so that they may meddle in this affair and save their fragile settlements from the depredation of the Blight.  Well enough.  I will give you the mnemosyne you seek if you do something for me..." Lord Rytheran tells you, "In the ancient garden below, my followers have gone mad, forgotten themselves and their allegiance to me. Regrettably, they had something that is dear to me in their possession when they lost their minds.  A ring of some... sentimental value.  Find that ring, and bring it to me.  I will give you the mnemosyne you seek when you bring me the ring.  You will have to kill me to get the mnemosyne otherwise, and I can already see you lack the power and the will to do that."

If you choose to kill Lord Rytheran (Lady Aerfalle briefly appears after he dies):

You bring Lord Rytheran to a fiery end! As Rytheran's battered bones collapse under the force of your assault, the undead lord's skeletal face seems to break into a bitter grin. Lord Rytheran says, "Fool! Are you truly willing to risk my eternal enmity, and the wrath of the formidable legions that serve me? Even if my memories fail me, the Web will remember..." A wind blows through the chamber, and the scattering of bones that was once Lord Rytheran of Menilesh vanishes. Another presence appears in the center of the room... Lady Aerfalle says, "My poor Rytheran, what have you done to yourself?  What perils were unleashed by your dabbling with that accursed book?  I am here now, and I will not let these mortal vermin sully your remains..."

The pillars surface feels cold and oily. A horrible taste blooms in your mouth and you hear a whispering voice. You realize the voice is coming from your own mouth, whispering words in a language you don't understand.

You give Lord Rytheran Ring of Remembrance. Lord Rytheran tells you, "Ah, a keepsake from my lady love... At last, a memory that will bring me some warmth in this eternal darkness. Take this mnemosyne, and my mask of office... And go.  Leave me to my memories." Lord Rytheran gives you Rytheran's Mnemosyne. Lord Rytheran gives you Visage of Menilesh.

You allow Lord Rytheran to examine your Rytheran's Mnemosyne. Lord Rytheran tells you, "I do not want this any more. The memories are too foul and terrible.  Better that I forget.  Bring it to your masters, who would surely find it illuminating."

Lord Rytheran tells you, "You have the mnemosyne your masters seek. Be off with you and bring it back to them.  I find I take little pleasure in the stink of your sweat or the sound of your beating heart."

You give Zho Heishan Rytheran's Mnemosyne. You've earned 297,235,856 experience. (Level 275) Zho Heishan tells you, "Amazing! You actually convinced Rytheran to part with his precious memory of the Book of Eibhil?  I do not know what you had to do to accomplish it, and perhaps that is for the best.  You have my thanks, and the thanks of the realm of Dereth for the good you have done here.  These memories will be invaluable in helping us solve the mess that Rytheran and that book created."

You give Zho Heishan Visage of Menilesh. Zho Heishan tells you, "This mask is... breathtaking. It once belonged to Lord Rytheran himself?  Truly a precious artifact.  If you do not want it, I can grant you some practical experience for it." You've earned 49,539,309 experience.

Zho Heishan tells you, "I believe you have served me already, have you not? I have no further tasks for you now, but I thank you for your attentiveness."

OR

You give Lacarra Avanthi Rytheran's Mnemosyne. You've earned 297,235,856 experience. (Level 242) Lacara Avanthi tells you, "Well done! I will not ask how you got this artifact from the hoary old tyrant.  But this should contain the information we need to find out what Rytheran did wrong, and what we can do to stop what he has unleashed..."

Lacara Avanthi tells you, "You've already retrieved Rytheran's trinket for me. I thank you for your service, but I have nothing for you now."

Zho Heishan tells you, "You cannot fool me. You've already sought out Rytheran on Nuhmudira's behalf.  Be careful of your associations.  The blood witch is treacherous and would think nothing of sacrificing you for her own ends.  I am afraid I can have no dealings with you."

Lacarra Avanthi tells you, "I can already tell that you've helped that groveling fool Heishan with this matter of Rytheran. Beware of the time when you are forced to choose between your own kind and the Empyreans who would enslave us all."
