Yeah I have looked myself. With how little they have out there I wouldn’t be surprised is their ES contract does not allow them to have any independent audience interaction. I mean there doesn’t even seem to be a source saying the names of the musicians.

This is probably super obvious, and you already tried, but I have to ask, Is there any way to contact them outside of ES? Does Wanderer’s Trove have a site, social media, etc.? If so, do they post any contact information like e-mail? If you get ahold of them directly they will be able to direct you to where you can buy their stuff without a third party if there is one.
