It's nice that Elder Scrolls Online will bring up to regions in Tamriel that I question will ever be seen in the main games. Although we see some of Black Marsh in the base game, Murkmire brings us to the land of the Argonians and I feel it explores their culture a lot better here. I said something similar when I played the Wrothgar DLC but Argonians were never an Elder Scrolls race I cared much about but now I have a new found appreciation for them. Seeing the visual variety of the Argonians was cool and I was intrigued by the different tribes that make up Murkmire. There's plenty of beauty to be found in the seemingly dank swamps of the region. The most interesting thing about the Argonians was always their connection to the Hist; a possibly sentient race of trees that guides the lizard folks' actions. I don't think we necessarily learn anything new about their relationship but I enjoyed seeing it on display throughout the DLC. The main villain being an Argonian desperate to make a connection to the Hist that they never had is a pretty good motivation for the course of the story. It's a pretty self contained episode with no grander arc and they make good use of the shorter story. There's a decent attempt to make the main quests feel different from one another even if ultimately, you're mostly just killing hordes with the same combat system as always. I did quite enjoy my time with it.
