Clue

Clue is a Mu Lung + Nihal Desert quest started by Carson.

Part of A Deal with the Broker: see every quest in order.

Requirements

Offer: What I want you to do now is to search the house of the alchemist that has gone missing. It's the very place where the accident occurred. We've already searched the house a number of times, but I'm sure there's still a lot that hasn't been found, especially De Lang's Secret Note...
That's why I want you to go there and find even the smallest piece of evidence. It'd be fantastic if you can find the Secret Note, but even if you can't, a nondescript sentence will be better than nothing.
Completion: How was the search? Did you find anything particularly interesting? Any clues?
...really? A pendant... a pendant... maybe that's...
No! It's nothing. We better find out more information about the missing alchemist. Thank you for your help. Now, if you'll excuse me...
