Most difficult locks

Exploration Stage: Cards of Fate
From: Martha
Description: It is as if each lock bears traces of life and personality.3 I think that is the "key" that reveals how to open all the locks. I just remembered that Houdini used to brag about opening the locks of some very difficult clocks. Add that to our analysis and I'm sure we'll get the missing astral data.
Completed: Wonderful...the numbers on this lock complete my astral formula! I now have most of Houdini's universal law in its entirety. Come to me later. I'll tell you the result.
