- Go to Nashkel and speak with Oublek in the center of town (just south on the road by the Temple)
- Accept his bounty request for two stolen emeralds
- Make your way to the Nashkel Mines via the world map
- Go to the south western border to find Prism
- Protecting Prism at this point will yield
- Otherwise let Greywolf kill him, he will leave the emeralds
- Loot the emeralds and return to Nashkel
- Speak with Oublek again, complete the bounty, and the achievement is yours
