While meandering through the sunny but war-damaged lands near Oxenfurt, Geralt's sensitive ears picked up a very strange sound - something between off-key singing and the bellowing of a stuck pig. Geralt would be a poor excuse for a witcher if he did not investigate such a matter.
It turned out the dubious musical talents belonged to a troll who believed himself part of the Redanian army. His fondest dream was for fort he had been assigned to guard to look like a proper Redanian fort. Bear in mind that a troll's mental capacity is roughly that of a none-too-bright toddler, and you'll understand why this particular one felt a Redanian fort should be painted in bright Redanian colors. Geralt brought him red and white paint, which made him as happy as a child finding a present under his pillow.
It turned out the dubious musical talents belonged to a troll. Geralt felt the monster might be a danger to people living nearby, so he decided to end its life.
