Warehouse of Woe - Novigrad
Location: Novigrad Docks
Quest Giver: Acquired on proximity to the area
Other Requirements: N/A
This quest begins in the southwestern portion of Novigrad Docks by a warehouse. You'll come across a Dwarf and a Human arguing about the building (pictured above) and you'll need to speak with the guard here to begin the quest. Note: If you choose not to get involved or accept the quest then leave the area you will fail it.
If you're having trouble finding the location this quest takes place at I recommend you use my screen shots above and below these paragraphs. For this quest you'll have to go inside of the warehouse they're bickering over and defeat the Nekkar inside as well as inspect the cage with bars sawed off and the foot print which appears to belong to a dwarf.
Outside you will have a few different options for completing this quest.... Here's all of them:
1. Tell the guard you don't know how the monster got in -- he takes the dwarf/human to his captain and lets him sort it out
2. Tell him you found the cage but not the foot print -- he takes both them away and locks them both up
Revealing the foot print and the cage to the guard will give you a few more options to choose from
3. Accuse the Dwarf. He denies the accusation and is taken away.
4. Accuse the Human. He claims you and the dwarf are working together then gets taken away. The dwarf will comment afterward that the human wasn't smart enough to come up with a plan like this.
