I've come into possession of a significant quantity of labradorite. I remembered what you said about your shop, so I came.

[Striding over to the counter, Walter reaches into the satchel slung across his body.]

As for why that couldn't wait... Well, a certain someone has decided to host a formal ball of sorts at the beginning of next month, and I want to take advantage of that to raise funds for charity. I figured dangling something shiny and potentially useful for magic would do the trick.

[That said, he pulls out a slab of labradorite roughly the size of the satchel itself, and sets it on the counter.]

I have over two-hundred more of those with me right now.
