Bygernwerth is an area situated directly past the Shadow of Yarhnam boss fight in Forbidden Woods. From the Forbidden Grave Lamp, head away from Forbidden Woods though an arched doorway into a narrow wooded tunnel. Keep an eye out for an ambush by a Mi-Go that is hiding behind some trees on your right at the end of the tunnel. There will also be a corpse with a Madman's Knowledge to your left. After you exit the wood path the Byrgenwerth Lamp will be directly in front of you.
There are 3 more Mi-Go Zombies in this immediate area; one patrolling the path at the bottom of the stairs directly past the lantern, one patrolling on the path to the far left of the lantern, and the last is behind a tree near the second patrol (down the stairs, turn left, turn left again and it's behind the tree at the end). It is better to try and pull them one at a time and avoid their flying jump/grab since it will induce frenzy. Keep some Sedatives handy.
The gate at the bottom of that first stairwell is shut for now but can be opened up to provide a shortcut later.
From the lantern head down the stairs, kill the first Mi-Go to your left and continue down that path to the left and dispatch the 2 Mi-Go there. After this, head up a small stairwell to the right, sticking to the left wall to acsend a small stonewalled path and some stairs into a clearing with a tree in the center. There is a Brainsucker behind the tree. Dispatch it carefully and then pick up the Arcane Lake rune near it.
Run back out of the clearing the way you came and you should find yourself next to another closed door on the side of a building. Head to the left, down towards the lake. Head down the central path under the bridge on this side of the building, being careful of the Celestial Centipede on the other side that may throw some fireballs at you. Pick up another Madman's Knowledge on your left which will trigger 2 more Mi-Go dropping down from the bridge above. Pull them back away from the Centipede and take them out.
Once they're taken care of head back to the Centipede, dodging its fireballs, and get behind it and just wail on it 'til it goes down; it is also susceptible to poison, so you may want to use Poison Knifes if you have any. Underneath the balcony on the left hand side you can find a Great One's Wisdom. Be careful, because there is yet another Mi-Go on the far side of the circular rotunda the Centipede is near. Deal with that Mi-Go next and pick up x5 Sedative on the far side of the rotunda where it was hanging out.
You should now head back towards the house on this side. You will see the other side of the gate by the Lamp and the lever to open it. There is also an open door leading into the building. Pull the lever and head into the building.
Inside you'll be on the ground floor of what appears to be some sort of lab. To your left will be a chest with a Pearl Slug. Directly ahead is the backside of a curving staircase that leads to the second floor. When you go around to the front of that staircase you will aggro an NPC hunter, Yurie, who's hiding at the top right of the stairs.
This hunter is a fairly difficult fight; she wields a Threaded Cane and a Rosmarinus and can also use an Augur of Ebrietas (tentacles shoot from her hand), and A Call Beyond (star explosion of magic, very annoying to dodge). Generally trying to stick close to her to bait a cane/whip attack and then dodging around her seems to discourage the magic attacks, but be warned that she can hit for a lot of damage. The stairwell can be used mostly reliably to avoid the star explosion attack, but her whip can hit you through it. It is possible to parry her, however the window for a parry is so narrow that unless your timing is impeccable, chances are you'll still take damage. The main issue with this fight is that there is no open ground to fight on, the furniture and layout of the house means that you can be cornered very quickly. Patience is key. You can always run over and open the far door before she engages you and pull her outside for more room to maneuver.
This NPC fight can also be initiated with a visceral backstab for some free damage. Go to the bottom of the staircase to trigger her, then back off and hide out of sight. She will walk down the stairs, turn around, and go back up again. When you sneak back up the stairs she will be standing in front of a chest with her back against you.
Once the hunter is dead you can open the (fairly useless) shortcut door on the other side of the room and safely head up the stairwell to the second floor. Straight ahead in the little sitting area is another chest with the Student Set in it. Heading back past the stair and around there is a door to the right that is currently locked (this is the door that leads to the boss fight) and then further on there is a note to read on a bookshelf. All the way around is a ladder leading up to the third floor that you should climb now.
The treasure on the table immediately in front of you as you climb off the ladder is the Lunarium Key, which unlocks the boss door on the floor below that you just passed. But before continuing on to fight the boss, head up another flight of curved stairs to a little landing. This landing will probably be empty now, but it is where the Chime Maiden who rings the sinister bell will spawn when playing co-op/PvP.
Head up yet another curved stairwell to the very top floor and watch out for a Mi-Go ambush from behind you. Open the chest up here to receive an Empty Phantasm Shell and then head back downstairs to the second floor. Open the locked door and head out onto the balcony to meet Master Willem and engage in deeply profound conversation with him. Talking to him nets you 2 Insight and killing him (no real reason not to) grants you the Eye rune. After you're done chatting/murdering, head to the far end of the balcony and hop off into the lake to fight Rom, the Vacuous Spider.
Note: If you have the League of Confederates patch and have acquired the Old Hunter Bell, then there is a summonable old Hunter called Mensis Scholar Damian. His summon location is right next to balcony door. He is very similar to Micolash in terms of fighting, except he primarily uses the Blacksky Eye and will heal you with a Choir Bell if you are low on health. If you have the Impurity rune equipped, the Younger Madaras Twin can be summoned near the lantern and Old Hunter Henryk can be summoned on the second floor of the building near the chest.
- The moon here never turns orange.
- There appears to be a trapdoor built into the floor of the building's lowest level. A chain worked into a small pulley on one side runs over the top of the door, precluding access.
- Many of the breakable containers inside the college contain eyeballs and a greyish liquid.
