Baltimore's Nightmare is a quest in The Witcher 2: Assassins of Kings.
- Locate Baltimore's house in Vergen: His house is next to Cecil's house beside the giant closed gate. Go there and a short sequence will be played.
- Discuss Baltimore with the dwarves working at the anvil: Talk to Thorak at the anvil.
- Search Baltimore's workshop: Go into the back of Baltimore's workshop, use an Aard spell on the collapsible wall (left of the back of the workshop) that leads to a little room. Inside the room you'll find a chest containing Baltimore's key and Baltimore's clue.
- Follow the clues from Baltimore's notes: Go to the quarry, you'll see a Elthon's hut. Go towards the cliff edges (on top of the rocks). Those rocks inscribed with runes are "Ingrand's signs". Now, following the arrows on the signs, go to the bottom of the quarry and towards the quarry door, but not quite to the door, bear left and uphill. There will be a chest containing Runic key inside. Loot the chest.
- After obtaining the key, go to the shipwreck at the southwest of the map (passing the Troll's Lair). There will be a hidden door behind the vine by the cliff. The door will be unlocked with the key.
- Once inside, depending on whether or not you told them the truth earlier. Thorak with company will show up immediately. If you told Thorak what the notes said, then they'll shadow you and initiate a conversation upon entering the hideout. If not, loot all the chests. There will be a chest with a Beaver cap and Baltimore's notes in it. An event will trigger once you loot the chest and Thorak and company will show up. After the short sequence, You will have the option to either kill Thorak to find out what's in the notes, or sell them to him for a discount at his shop. Should you choose to kill them, loot Thorak's key from Thorak's body.
- Inform Cecil Burdon, the elder, about Thorak's crime: Go back to Cecil in Vergen to claim your reward: Gwyhyr.
- Geralt witnessed various wonders in the harpies' nest. Among others, he saw the dream of Baltimore, a dwarf who had once lived in Vergen. Baltimore was now dead, his dream - in which he was running in terror - having become a reality. Before the witcher would discover that, however, he would have to find the dwarf's house.
- Geralt found the building from the dream. It looked like a workshop. He was about to enter it when he noticed some craftsmen working at anvils nearby. The witcher decided that if anyone knew anything about Baltimore's fate, these dwarves would.
- Geralt was right - the building from the dream had indeed been Baltimore's old workshop. His former home stood right next to it and was now occupied by a dwarf named Thorak, Vergen's new rune master. The witcher learned that its former owner had vanished without a trace years ago and was considered dead. The story intrigued Geralt. He knew Baltimore had been living in fear, so he suspected there might be a secret behind the dwarf's disappearance. He decided to investigate and started by conducting a thorough search of the abandoned workshop of the former rune master, who had experienced the terrible nightmare.
- It appears that dwarves tend to hide maps and keys in old furnaces. Geralt cleared the soot from his discovery, and the curious Thorak did not voice a single objection to his destruction of the furnace. The note was written in Elder Speech, a language the witcher knew, of course. It said: 'Start looking at the well where loud echoes dwell. Take ten paces t'wards the river, a walk left and do not shiver. A meager two tens of paces, pass the gate in my good graces. The one that our safety keeps. Go where teh crossroads' patron sleeps. Every road you need to take, yet the middle one is safe. Heed and look for Ingrand's signs, and you'll follow my designs. Should you choose to go right, you'll soon see someone in plight. At noon this drowned soul points its shadow at your goal'. Geralt knew that an Ingrand's sign is the symbol of the patron guides, shaped like a circle with a line traced from it. The line always points to a shelter.
- Geralt understood that Thorak was only feigning indifference and in reality was very interested in his search. The dwarf was not to the witcher's liking. Our hero decided to continue his investigation while keeping an eye on Thorak. First he deciphered the notes.
- The witcher found an Ingrand's sign. He went in the direction pointed by the line.
- Following Ingrand's signs, Geralt found a key hidden by Baltimore. Now he needed to find the lock which the key fit. The witcher looked at the notes and followed the second path.
- Thorak shadowed Geralt the whole time. He had a guilty conscience. The letter found by the witcher was irrefutable proof that Thorak had killed Baltimore. Our hero decided the Vergen elder should learn of this.
- Cecil Burdon was shattered by the news of Thorak's crime. In one stroke a murderer was discovered and a rune master lost. The elder began to ponder the situation, yet he did not forget to reward the witcher for solving the mystery.
