I LOVE the fact that they used music and sound files from Morrowind! I feel like I traveled back in time, but with newer graphics!

Raven Rock: I clearly remember helping the East Empire Company in the construction of Raven Rock in Bloodmoon (the Morrowind Expansion). I can't wait to visit Fort Frostmoth again. Although, I'm sure I won't receive a warm welcome.

Rieklings: LOL I tried to search a barrel and suddenly it busted open and one of their hunters attacked me. I totally forgot about that!
Stahlrim: Wow, I totally forgot about Stahlrim! I remember I've found quite a bit during the Bloodmoon expansion and it was also found in crypts.

Water Walking potion! OMG I was giddy as a kid in a candy store, when I found a Water Walking potion! All that's missing is a levitation amulet!

Neloth and the Telvanni Tower Mushroom! Never thought I would find something like that on Solstheim, but I guess with Red Mountain erupting and all, it's plausible that some Telvanni moved to other parts of Morrowind. I could just float up and down in that tower shaft all day! LOL I love it!
Bethesda truly went above and beyond with this DLC!
I love that voice I hear, when I touch one of these shrines! I guess it's Miraak?
Oh and when I picked up the Black Book, I sure looked surprised.

What triggered your memories, if you have played Morrowind, Tribunal and Bloodmoon?
