A recurring green hag character across our d&d campaigns, a curiosity/magic shop owner named Mora. Mora’s shop can mysteriously pop up anywhere there’s a large enough city, and she always manages to have rare components and unique/interesting items in stock.

She also, importantly, has a mail-order catalog. In traditional campaigns you can pick up paper catalogs at her shop. The Old Crone’s Catalog can be filled out and burned in a fire pit with the appropriate amount of money (which magically disappears) and your items will be delivered by Raven within a few days.

In modern times, you can just download her holophone app.

In the Thooniverse she works closely with Auzzimaks. He makes magic fragrances and salves for her to sell in her store in exchange for access to rare and exotic ingredients at an exceptional discount. She drives a hard bargain.
