Weird little dolls in the crypt?

In the Crypt of Bersault, I came upon two circular rooms that had stairs that descended into the floor. I had to use a crystal to keep a staircase above ground, but could only do one or the other staircase. At the top of the staircases is an altar with a burning flame on top of it, and a small runed idol in its center. I chose the red one (Wizard's Jindol). What are they for, and does it matter which one you grab? Thanks in advance for your help.

Each doll goes in a certain urn which will determine your path. Have heard you can pile up chests, crates, etc to reach the other but you will have to go through twice because each path is a one way trip.
