Behind the lantern, go down. You will be attacked by an enemy (be careful not to get caught by the strong attack). In front of you, there is a gate which you will unlock later. Turn left and watch out for another two enemies. Keep them at a distance, preferably using an extended weapon. If you're not in a hurry, you can wait until one of the enemies goes up the stairs and you can fight them one by one.
A bit higher, you will reach a place from where you can see a building below you. However, first turn left, where you will find a single enemy behind a tree (watch out for a blue missile that will stun you if you're hit). You can ambush the enemy by going around the tree, thus gaining advantage at the beginning of the battle. In the body, you will find Arcane Lake rune which reduces damage received from Arcane attacks.
Go down towards the building. You will be attacked by two enemies (step back and keep your distance from the opponents all the time). After killing them, you will encounter a large monster. Approach it as quickly as you can - otherwise, it will continue shooting fire missiles at you. When you're close to the enemy, it will only attack you by spitting out some goo, which you can notice before the attack (an opening hole in the center of the body). After defeating the beast, you will obtain Numbing Mist and you will also find Great One's Wisdom in a body near the barrier on the left.
Now head straight towards the monument (you will be attacked by a single enemy). Near the edge, on the left, you will find 5x Sedative. Go up the stairs and unlock the gate at the end of the road. Turn right and head into the building. On the left, you will find a Pearl Slug and you can open another door. Head down the stairs, where you will be facing a hunter.
Drag the enemy downstairs as soon as the battle starts. He fights using a sword and sometimes a whip. Also, watch out for the attack when he throws some powder at you (it happens when you stand too long in front of him), because it's the one that deals the most damage. Another special attack starts with the enemy crossing his weapons and summoning electric projectiles. What's the most important, try to avoid the attacks described above, focus on keeping your distance from the enemy and attacking by jumping towards him. When the hunter throws "tentacles" in front of him, it is a good moment to attack - if you dodge this special attack, you will have a moment to jump close to the enemy and strike a few blows.
After the battle is over, head upstairs. In the place from which the hunter came, you will find a note lying on the sofa. You will also find Student Uniform and Student Trousers in the chest. Now turn around and walk to the end of the room to read another mysterious note. From below the shelves, head left and go up the ladder.
Upstairs, pick up the Lunarium Key from the table. Walking up the stairs, to the top, you will encounter another enemy. Open the chest to find the Empty Phantasm Shell. Go downstairs and open the door located on the left side of the room.
Outside, "talk" to the bishop on the wheelchair. He will point at the edge of the balcony. Jump into the water and you will be teleported to Moonside Lake. The only thing that you will do here is fight a boss - Rom, the Vacuous Spider.
Note: For killing the sitting NPC, you will receive a rune - Eye; this killing has no further consequences.
Note2: Defeating Rom, the Vacuous Spider will result in a day time change. Some quests may become unavailable, because of, e.g. the disappearance of the character from their regular location. On the other hand, moving the story forward will result in some new quests becoming available.
After you win the battle, the time of the day will change. You will also unlock a passage to Yahar'gul Unseen Village (after the fight, approach the edge of the lake).
