The other night I finally got around to completing the Greymoor map and questlines.
I still have things to do in Western Skyrim, such as achievements and collectibles related to the two public dungeons and the bard's college, not to mention fishing.
But the zone guide displayed to the left of the map is 100% complete.
Despite all the negativity that a lot of players have directed toward Greymoor, I found it to be rather enjoyable. Was it perfect? No. But I still enjoyed it. Western Skyrim is a nice zone to run around in, and Blackreach is challenging to explore. Tracking down that darn elusive skyshard in the Lightless Hollow without resorting to an app or online map was quite challenging, so it felt like more of an achievement when I finally found it.
Now I just have to complete Markarth before Blackwood is released.
I've fought mudcrabs more fearsome than me!
