After the previous mission in the Urshilaku Camp, The Nerevarine must speak with the Spymaster Caius Cosades to receive new orders. The Spymaster says that a Sixth House base has been discovered near Gnaar Mok, and that a group of Imperial Soldiers from Fort Buckmoth were hgoing to raid the cavern, but the Sixth House forces overwhelmed them. However, the local Sixth-House's commander, Dagoth Gares, spared one soldier's life, so he could go back to the Fort and warn them about Dagoth Ur's return. The soldier died some time after the incident, killed by the Corprus disease.
The Fort is located on the southern outskirts of Ald'ruhn. The Nerevarine must ask about the incident to Raesa, she will, then, give more details, explaining that the Sixth House base is inside a cavern named Ilunibi, she suggest speaking with the Gnaar Mok's residents about the cave.
The Sixth-House base, Ilunibi, is located north of Gnaar Mok, in a little island, accessible by foot. Inside, there are many leveled Corprus creatures, Sixth-House Dreamers and some Daedra creatures, moreover, the cave is very dark.From the first area entered, Carcass of the Saint, the Nerevarine must find their way to Marowak's Spine . There is an optional sub-location called Tainted Marrow. Marowak's Spine leads to Blackened Heart, and then, to the final location, Soul's Rattle. In Soul's Rattle, Dagoth Gares will be waiting for the Hero. He will not attack immediately, first he will have a conversation. Explaining that Ilunibi is just a little base with lesser servants, he will then expand on Dagoth Ur's plans, and will give the Hero a message from the immortal High Councilor himself:
Dagoth Gares will say that as long as the Nerevarine is not a Sixth House member will treat them as an enemy, and offers that the Hero submits to Dagoth Ur in his Citadel in the Red Mountain Region. Gares will, then, turn hostile. Dagoth Gares is not as powerful as most Ash Ghouls. Once Gares is defeated, he will curse the Nerevarine with Corprus disease, then dies.
After collecting all the valuble loot in the caverns, it is now time for the Hero to go back to Spymaster Cosades, who is worried about the Nerevarine's health.
- Note: Now infected with corprus disease, it will be difficult to get services from many people, as they will not want to be near the Nerevarine for fear of contracting the disease too.
- Promotion to next rank in the Blades.
|Sixth House Base|
|Before I take my next mission, the Spymaster wants me to improve my skills. He suggests I take a few guild jobs, cash in the loot, and upgrade my equipment. He gave me 400 gold to spend. When I think I'm ready, I'll go back to him, and he'll give me my next mission.
|The Spymaster has sent me to find a Sixth House base near Gnaar Mok. There I must kill a Sixth House priest named Dagoth Gares, and bring the Spymaster a full report on the Sixth House base. But first I need to speak to Raesa Pullia, the Champion of Fort Buckmoth. She'll tell me about the patrol that found the base, and how to find it.|
|I spoke with Raesa Pullia. The trooper who escaped died mad and disfigured with corprus. The cavern with the Sixth House base -- Ilunibi -- is not on the maps. I'll ask in Gnaar Mok about Ilunibi. The patrol fought cultists, disfigured man-beasts, and a half-man creature named Dagoth Gares. Dagoth Gares killed all the patrol, but sent one survivor out with messages about awakened sleepers and Lord Dagoth Ur.|
|A scout in Gnaar Mok told me about an old sea cave, called Ilunibi Caverns, up on the north end of the Gnaar Mok island, right on the coast. He said there was nothing but rats and slaughterfish, though smugglers and outlaws might use it for a hide-out.|
|The priest of Ilunibi Shrine tells me that Dagoth Ur bids me come to Red Mountain, where he would grant me counsel and power, if only I would pledge that friendship anew. He says the path to Red Mountain is long, and filled with danger, but there I will find wisdom, a firm friend, and all the power I need to set the world aright. So Dagoth Ur hopes to attract me to his service with promises of friendship and power.|
|Dagoth Gares says the Sixth House was only sleeping. Now Dagoth Ur and the Sixth House will free Morrowind of foreign rulers and divine pretenders. When the land is swept clean of 'false friends' and 'greedy thieves', the children of Veloth 'will build anew a garden of plenty in this blighted wasteland'. So the Sixth House means to drive out the Empire, overthrow the Temple, and restore the pre-Imperial Dunmer nation of Morrowind.|
|Dagoth Gares describes the Sleepers and Dreamers as new and weak worshippers. But the Children of His Flesh -- I think he means the corprus beasts -- are 'deep in the heart of his mysteries'. He also says that he and the servants of Ilunibi we are the least of Dagoth Ur's servants, and that servants called 'Ash Poets', 'Ascended Sleepers', and 'Ash Vampires' are more powerful and more blessed by Lord Dagoth.|
|Dagoth Gares says Lord Dagoth would far rather have me as a friend than as an enemy. But until I submit to Lord Dagoth, Sixth House servants will treat me as an enemy. If I want to be a friend of the Sixth House, first I must go to Lord Dagoth in his citadel on Red Mountain, and make my submission.|
|Dagoth Gares says Ilunibi shrine is only a small, quiet retreat where Sixth House servants share the sacraments of flesh and blood, and dream the dreams of their Lord. He says other lesser shrines are hidden throughout the land, but the greatest shrines of Sixth House servants lie beneath Red Mountain, in the citadels of our Lord and his close kin.|
|Dagoth Gares addressed me as if I were Lord Nerevar, giving me Dagoth Ur's words. Dagoth Ur says Nerevar and he were friends and brothers, but that Nerevar struck Dagoth Ur down beneath Red Mountain while Dagoth Ur protected a treasure Nerevar had sworn Dagoth Ur to protect. Yet Dagoth Ur offers to forgive me and raise me high in his service. So Dagoth Ur thinks I'm Lord Nerevar. I wonder about their history together.|
|I have killed Dagoth Gares, as the Spymaster ordered. But with his dying breath, Dagoth Gares pronounced a curse on me, and now I have the corprus disease. He said I would come to Dagoth Ur ' in his flesh, and of his flesh'. I don't feel any different, but the marks of the disease are plain on my face. I'll have to return and report to the Spymaster on the Sixth House base, and hope he knows of some way to cure this disease.
