Learn how to complete the investigation quest Ambition in the Ruins in Crimson Desert. This guide will provide the correct answers to the investigation you report to the Calphadean Defender.
Where to start Ambition in the Ruins
You can start The Weight of Knowledge by first completing Chapter VI: Cracks in the Shield. Once Calphade has begun reconstruction efforts, talk to the Calphadean Defender at Calphade Castle’s north gate.


Investigating the Theft
Someone is stealing construction materials meant for the reconstruction of Calphade. Talk to the various people the quest leads you to, then return to the defender when you’re complete. You’ll need to answer with:
- The quartermaster and the merchant are suspicious.
- The workers and the blacksmith are all working till dawn.
- Didn’t look too happy with Caspar.
- The lad seemed troubled, with all the iron coming from who knows where.
- The supplies they received were in poor condition.
- He seems to take pride in the things he craft.
After talking to the defender, you’ll need to bring in the culprit to complete the quest.
Reward
For a reward, you’ll receive 100 Hernandian Contribution and the Kinetic Dolphin decoration. Despite being labeled as a dolphin, it’s actually a humpback whale. It’s divided into several segments that move up and down through the spinning gear to mimic the motion of swimming.
