I did a test install of Emissaries of Tux, the modlist by the same dev who brought us Tuxborn for Skyrim. Since there isn't a formal install guide for how to install Emissaries on Steam Deck yet, I wrote this post up to cover my notes for how it worked for me. Emissaries is not currently installable due to a mod in the list going into Nexus mod review, but bookmark this post to refer back to when the list can be installed again.
