Walkthroughs for the quests from Helgen Reborn, a user created plugin for Skyrim. Following the elimination of the vampire threat in Shriekwind Vampires, the next mission in The Changing of the Guard is to deal with necromancers.
The Changing of the Guard (Brittleshin Necromancers)
"A new necromancer leader has moved into Brittleshin Pass and no one can use the passage to get through the mountain. Korst has asked me to take Joto/Cidius/Savard and eliminate the threat."
There are rather more enemies in Brittleshin Pass than there are normally, as well as multiple dead bodies, making the location much more dangerous. Given the sheer number of Necromancers, it is likely that any that die will likely be turned into zombies by the survivors, as well as any existing dead bodies being reanimated into zombies.
In total, there are twelve more corpses, including two Vampires, a Werewolf and a Hagraven, three more Skeletons, seven more Necromancers, a Fire warlock and a Shock warlock, all levelled, in Brittleshin Pass. Open confrontation with them is likely to be rapidly fatal. There is a new area, Brittleshin Cavern, which is where the actual target is.
Enter Brittleshin Cavern, which is also inhabited by a lot of enemies; five Necromancers and a Fire warlock, as well as three Skeletons. There are six dead bodies, including a Hagraven, which can all be reanimated as zombies, as can those of any enemies who fall in battle. Again, open confrontation is not recommended.
As you enter the cavern there is a raised bridge, which needs lowering. Make your way down to the floor and then through the tunnel to the west which leads up to a chamber with an Alchemy Lab. There is another tunnel leading up to the east with a Lever at the top. Activate the Lever to lower the first bridge, then make your way back to it and cross. There is then another raised bridge and a cave off the west with another Lever in it. Activate it to lower the second bridge, then continue south to the final cave where the target, a very hard levelled Necromancer, is waiting. Kill them, and then return to Korst.
"The necromancer threat has been eliminated. I should return to Korst and give him my report."
If you are doing this quest with Joto, as you are making your way back through Brittleshin Cavern after killing the boss, you will come across a Stray Dog, which Joto will adopt and name Bhisha. Bhisha will then be seen following Joto around.
"The bandits that once occupied Helgen are regrouping and planning on attacking to retake the fort. Korst has asked me to take Herd and eliminate the threat."
Find Herd and go to the Upper Pinewatch Mine, a new area. This is a pretty straightforward killing quest. You need to kill the Bandit Boss, but there are lots of various types of Bandits, who can overwhelm you with their numbers if you aren't careful. There are twelve Bandits outside, including a Bandit Wizard, and the Alteration skill book The Lunar Lorkhan, as well as other treasure.
Enter the mine and, straight ahead from the entrance, is a Bandit. In the large chamber to the right are two more Bandits, one of whom is armed with a bow and is on an upper platform which can't be reached from the cavern.
The way to the boss is to the left of the entrance as you enter. There are three Wizards, eleven other Bandits, a Dog and the very hard levelled Bandit Boss in this part of the mine, as well as a number of oil traps. Make your way to the boss, avoiding the oil and using it against the enemy when possible. Charging through is not recommended, due to the numbers. It is possible to take the high ground using some platforms, which will give you an advantage.
Once the boss is dead, return to Korst.
"The bandit threat has been eliminated. I should return to Korst and give him my report."
"A new owner has recently purchased a long abandoned mine near Helgen. The owner says there are stories that the mine is haunted and he can't find anyone who will go to work for him. Korst has asked me to take Orianthi/Josslin/Kar with me and investigate the mine and report back with my findings."
Find the relevant soldier and make your way to the Upper Embershard Mine, a new area. This is the most dangerous mission so far, possibly of the entire quest series, so stocking up on Magicka, Health and Stamina potions is a very good idea.
Make your way to the Upper Embershard Mine and enter it. When certain points in the mine are passed, dangerous monsters will appear and the screen display will become distorted. These also cause the screen to be affected until the monster has been killed, even if you leave the mine. The enemies in the mine are primarily undead, with the exception of the boss, who is a Dremora.
Once the final chamber is entered, a Dremora Warlock appears and the exits are blocked by invisible barriers. The Dremora is extremely dangerous, as he can heal damage and seems easily able to detect you. The Warlock casts what appears to be a Frost Rune spell constantly on you, which can quickly kill you. Finish him off as quickly as you can.
"The Upper Embershard mine has been cleared of its ghostly occupiers and it is now safe for mining operations to resume. I should report back to Korst and give my report."
As you make your way to the exit, Hanna will appear once again and thank you. She also gives you Hanna's Ring, which gives a 40% bonus to Sneak.
Return to Helgen and speak to Korst again, to continue with the next mission to defeat the Staadomaar Dragon Priest.
