- Bring ten pieces of garnet to the well-connected bartender in the Gnawed Noble in Denerim for "K."
Untraceable is a quest you can get from the Favors for Certain Interested Parties board.
Background
Note on the Rogue Quests board:
- A little something from "K."
- Seems some people just can't play fair. Make changes to benefit everyone and all you get are glares from the old men. No more toys for me, it seems, unless an enterprising friend cares to make a strategic donation, something nondescript that can be moved by small vendors. Garnet. Let's say ten pieces. Can't trade money for money, but I'm generous with my gratitude.
Walkthrough
Gather 10 pieces of Garnet in the game. You can find them in containers or when pickpocketing or you can check merchants. When you have 10, turn them in at the Bartender.
Important note - In order to turn this quest in and collect your reward, you must complete this quest prior to completing the quest Harsh Decisions. If you complete Harsh Decisions first, "K" will be dead. Therefore, you can no longer collect your reward from him for the Untraceable quest. The Untraceable quest will even disappear from your quest log.
Result
1 
- Thus purchasing garnets is not cost-effective
