On an especially sweltering afternoon as Ellis is leaving to attend to a shift of guard duty, Wysteria reminds pauses in the process of coating a piece of paper in a highly poisonous substance (it's fine; she's wearing gloves) to call after him, saying, "Oh Mr. Ellis! If the day is too warm, I believe there may be something in your satchel which will help."

In his bag is a small parchment wrapped shape. It is the same small dog carved from dark wood. Scrawled on the parchment is—

Hold this and say 'Good dog.'

-W.A.

And in reply, the surface of the carved dog chills like a river stone. It wears off after a few hours, but should last the length of a guard rotation at least.
