Tupperware is a plastic airtight container.

V... the can. What are you waiting for?

Did you find all of the vessels?

Do not interrupt the ritual. Go empty the vessels and sit on the throne.

A small container, made of the magically infused snow that first fell on the Throat of the World.

You've found the vessels. I worried that I had sent you to your death.

Very well. Empty the vessels into the sconce near the throne, then sit in the throne.

Silver cylinder… Bottom looks like what I found in the sewer…

Empty container… Painter can't use this.

Silver lid… Matches the cylinder bottom I found in the sewer…

Bottom of a silver cylinder, probably. Covered in runes… Interesting… Any idea what it contained?

Hm. Bottom of a container. Silver cylinder, most likely. Runes etched in the bottom. It's warped, probably by the explosion.
