Travel Companion

Exploration Stage: Laboratory
From: Detective
Description: Did we really find the Laboratory of Time? If this is the same laboratory that the Collector wrote about, the City clearly wants us to finish his investigation. But why? We need to find out if time really was studied here. We've stumbled upon a warehouse of weird artifacts and who knows what. Look for something among the devices related to the study of time, so that we can hopefully understand the purpose of this thing. There are so many kinds of mysterious items all around though... What about an unusual calendar?
Completed: Interesting thing you've found, pal. I think it's called "Kepler's Calendar". An old invention that's still in use today, a calendar that fits any year. Clearly this thing was often in use: just look at how worn the discs are! I wonder, how did this calendar help the owner of the Laboratory in time experiments?
