Mason is a friendly merchant from Tilley, specialised in selling various artefacts he has gathered on his adventures. One could find him on the old town's marketplace whenever he had something interesting for sale, usually coming with just a handful of items.
In recent years, probably due do his old age, he hasn't been seen as often on the markets. He was last seen in Tilley a few months ago, telling only Vintina Leite that he had some things to deal with out of town following the passing of a family member. He hasn't been heard since or seen since.
