Tes4Mod:Oscuro's Oblivion Overhaul/Shadows in a Struggle for Power

Detailed Walkthrough
This is a complex quest involving several factions, with several ways to start it. All the factions (the Bosmer Rangers, the Raiders (led by Hlofor the Arctic Bear), the Sylvan Rangers (led by Eregor), the Putrid Hand (led by Master Lien Valeth), necromancers (led by Fayth Noor), the Mages Guild, and the daedric prince Molag Bal) are after an artifact referred to as "Graithlan's vessel", which is actually a set of armor infused with his soul (the Dread Armor mentioned above). Whosoever wears the armor gains great power.

The easiest way to start the quest is to read one of the notices posted in Anvil. There are also reports and journals scattered in various locations (see below), or you can gain a journal entry by trying to don some of the sylvan rangers' armor.

From here, the easiest way to explain the quest is to deal with each faction individually:

The sylvan rangers and Bosmer Rangers are fighting in the Gold Coast area. The Bosmer occupy several camps (all of which have reports), while the sylvan rangers have taken over a handful of Ayleid ruins and are searching them for clues to the armor's whereabouts. Eregor has stolen the Heart of the Wild Woods, an artifact sacred to the Bosmer for reasons that are unclear (perhaps he plans to give it to Molag Bal?). If you try to don some of the sylvan rangers' armor, you'll receive a vision sent by Jephre, the Bosmer god, which prompts you to go to Narind and recover the gem (it's on a pedestal on the second level, guarded by Eregor's lieutenant Lareil). Once you do so, you'll receive another vision sending you to Yeleri, where Eregor himself is holed up. Killing him will grant you Jephre's favor and add you to the creature faction - meaning, most animals will no longer attack you. Additionally, he wears most of the Dread Armor (minus the helmet, which is currently elsewhere).

In the Nibenay Valley, east of Bravil, many forts have been taken over by Raiders led by Hlofor. He's based out of Dasek Moor, and has sent his children Faran and Sheil Hestarius to Fort Flecia and Fort Facian, respectively, to look for the Dread Helmet. Again, there are reports at all three locations; kill all three of them, and you'll take care of the raider faction. The helmet, by the way, is located in Fort Facian.

The Putrid Hand can be found in several ruins (see their entry), but the only one of interest is Wendelbek, where Lien Valeth is based. His journal has, among all the ramblings, information on the other factions and the armor.

Fayth Noor (who, despite the name, is male) has taken up residence in Underpall Cave along with a small contingent of necromancers.

Hannibal Traven doesn't really appear in this quest, but he does have a journal in his chambers, on the table beside his bed.

Once you have the full set of armor, toddle off to the frozen north, to a remote ruin named Varastal. The door there will only open if you're wearing all the pieces, so be sure to do so. Head inside, and you'll be confronted by the Reaver of Ghuul Icxth, guardian of the Icxth sword that goes along with the armor. With that in your possession, the armor will reach its full potential and proceed to take over your soul - ahem, provide you with many more hours of fun gameplay.
