The Coldest Sleep

Overview
Faction: Dark Brotherhood Quest Giver: Dead Drop Orders #6 Reward: 500

Walkthrough
The target is a Nord named Havilstein Hoar-Blood and he is five levels above you. Beware of his magical battle axe and his pet wolf. They can be found on Gnoll Mountain, outside of Bruma. The way to where he is can be really challenging. If you don't have a horse, you will have to find the path to reach him because he is on the top of the hill. Your target is camping outside with his wolf, and they will strike you once they see you. For an assassin that can't take him down in head-to-head combat, run down the mountain and watch him clumsily fall to his own death while trying to swing at you. Loot his axe and you can sell it for a lot of gold coins.

The dead drop location is very very tricky. Presuming you already have at least Buoyancy spell under your belt or at least a scroll or an amulet that enable you to breathe under water. You get the Buoyancy spell when you do the mage recommendation quest to retrieve Ring of Burden on Cheydinhal Recommendation. The chest is behind a lock gate submerged under water. Because you can't cast a spell under water, you need to find a Rusty Key in a chest. Go around the dungeon and you will find a lot of Marauders attacking you. Once you arrive at a very large room with some sleeping bags and chest, you will be attacked with at least 3 Marauders. Kill them all and one of them has the Rusty Key to open this gate. Once you open the gate, you can open the chest to get your reward and the next target for the quest.

The next Dead Drop will be at Nornal. After entering, there will be a locked gate that can be picked open with a lockpick. There is also a way to jump through the metal bars.
