This is the moment I'd suggest we start sacrificing.

Also, Tarvin, Misha and Vincus each find one bell.
[hider=Knowledge check: Rare lore.]
The white gold bells dropped by the unfettered are a rare gift, it makes no sound unless you absolutely need it to.
When sounded it's owner shows up and grants one favor.

Since it's a boon from my own god I'll have Misha pass the object on later in the story. Don't know to who yet.[/hider]
