Shrine

The Shrine is a utility that can be built at a Mason's workbench, usually late game as it requires an Ogreite as one of its components. Once built, right clicking the shrine presents you with several options for offering or sacrifice. Selecting one will task a citizen to it. The citizen will pause at the shrine, and then go to retrieve the selected item, returning with it to destroy it at the shrine.

The Shrine's description lends some insight to its operation.

Earthly Bonds Greed Gluttony Soul

The shrine will light up portions of its surface if sacrifices are made in a certain order. Start with an offering of Mud, then Coins, then Animals (In my attempt, the citizen retrieved two Bulls).

At this point, I am uncertain and further testing is required. "Soul" to me would imply human remains, and i found out that's true (I actually starved a townie to get the remains) now the whole thing is glowing and that's as much as I know.

If you've gotten farther than that update this please.
