1.) How many unique weapons/artifacts have you all come across? So far, the only ones that I have found or read about are the Champion's Cludger, the twin Scimitars, the Bloodskal sword, and Miraak's weapons. The Nordic and Stalhrim weapon sets are fantastic, but I'm a huge fan of finding and collecting artifacts.
2.) Are there any important items in Apocrypha? The only one that I came across was the spell tome for summoning a Seeker.
3.) Is there anything special hidden within the ruins of Castle Karstaag? I expected to find something really badass at the end of that dungeon, but all that I found was a throne with skeletal remains in it (while the Bloodmoon throwback is cool, I would've liked a bit more of a reward or at least more of a challenge). I'm just hoping that I may have missed something
