Martimius is Marty, a mod author who’s mostly known for their work on Serana Dialogue Add-On (SDA), which improves Serana as a follower and NPC, making her feel more organic within the Skyrim world. It’s quite an expansive and ambitious project, and Marty does have a lot planned in addition to the plethora of features it already has (radiant dialogue, quest commentary, romance).
