Silent Forest Ancient Necropolis Secret Quest
Found a dead body, next to a Moonlight Anvil, on the second tier of the large central structure in the Ancient Necropolis. Examining the body gave a note, which says,
"I've assembled all of the pieces, but still can't decipher what they're trying to say. My time has ended, but whoever finds
this letter, please do the honor of finishing my work. Uncover the secrets of the royal tomb that I could not"
Tried to use the anvil, but it says, "Not enough Purified Blade". Couldn't do anything with it, so headed down into the next tomb, just North of this main central structure. Inside I found another item I could interact with. Upon examination it says,
"I found purified all five cursed items, but it's still not over. What else do I need? The five items, and...I have to get moving. I
don't even have time to think, just act."
Looking at the map, you can see that there are five tombs surrounding the central structure. So I still started killing the the Cursed Warlocks in here until they dropped a Cursed Spellbook. Moving counter clockwise from here, i killed the mobs in each tomb until I had received a cursed item from each of the five; Cursed Spellbook, Cursed Blade, Cursed Wolf Claw, Cursed Armor Piece, and Cursed Fog. Also noticed that in each of these 5 tombs, there is a large Royal Tomb door that you can interact with, but says that you need a Royal Tomb Key.
In the last tomb, the one with the Cursed Mistfiends and the level 30 named mob, there is another item you can interact with, which says,
"I found it! I found a cursed item on a smokefiend slain by a traveler. At first, it seemed to have little value, but then I
remembered something. A certain lake can purify curses...but only at it's absolute center. I don't have much time. I must get
there before the curse spreads to me."
Taking all five of the cursed items, I swam to the bottom of Soundless Lake, directly in the center. This is the same place another quest in the zone takes you, not long before moving on to the next zone. At the bottom of the lake, you find a large circular alter-type structure. Use the cursed items while down there and it will purify all five of the them. Once purified, head back to the large central structure in Ancient Necropolis and use the anvil. This will consume all five purified items and give you a Royal Tomb Key. I used the door in the tomb directly north of where I was, but figure it will work in any of them. The door disappears and leads down into another area with level 35 mobs. They had 8-11k hp, so be prepared. After killing my way down, you come across a large central chamber, and inside is Umbra's Spirit. A very large, 35k hp, mob. Am doing this all solo, and guildless, so no back-up to call on. So if anyone kills him, let me know if drops anything interesting.
