REQUIREMENTS

It would be a good thing if you had completed "Contract: Phantom of the Trade Route" and cleared Wyvern nests before taking this quest to avoid bugs that might occur but it's not necessary.

This mod was created on vanilla game without any mods (except those required by tools). However, it dynamically upscales/downscales enemy levels based on player's level so I strongly suggest to remove all non cosmetic mods that changes gameplay or it's mechanics.

GENERAL INFO

This mod uses extracted Witcher 2 English (ONLY) voicelines for the most part. They are not present in Witcher 3 game so I advise to set English language for both audio and subtitles. People willing to translate see below.

Quest starts in between House of Respite and Nilfgaardian Camp in Velen:
