It's all in his hands

Exploration Stage: Silent Chambers
From: Sim Van Eijkel
Description: My identity can be verified using my palm prints. These cannot be replicated. If there’s a palm print recognition device, the mansion should be able to recognize me. Could you please bring one over?
Completed: Wonderful! This authentication device is a rare artifact in and of itself. Only those descended from Van Eikel can use it to access the mansion’s control system. Let’s have some tea prepared at the mansion. That way, we can continue our conversation in a more relaxed atmosphere.
