Important Choices & Tips

- Helping Faen: This path emphasizes stealth, lockpicking, and careful movement. It’s ideal for players who enjoy sneaking around.
- Helping Percius: This route involves more direct action and combat. It suits players who prefer fighting their way through problems.
Your choice slightly affects how certain guild members view you in future quests, but it does not prevent you from completing the full Thieves Guild storyline.
Pro Tips:
- Bring plenty of lockpicks — you’ll need them for several locked doors and containers.
- Use stealth abilities (crouch often) to avoid detection by guards.
- Pickpocketing NPCs while exploring Glenumbra helps raise your Thieves Guild reputation faster.
- The quest is recommended for players around level 6–10.
Completing this quest advances the Thieves Guild storyline, rewards you with gold, experience, and guild reputation, and unlocks the next mission, “A Double Life.”
