Here's why. I wanted to use that axe that's effective against elves to kill some Thalmor. At their base in Skyrim. I haven't started the Main Quest and never will on Gutslit, but I found out the only way to kill any at that base prior to the party during the main quest is killing the ones patrolling the walls. The problem is, I can only kill them if I shoot an arrow through the holes in the fences surrounding the walls. This would be fine, except for the fact that you can do this and it's almost as if they are static NPCs who don't exist.

They'll die, but no one cares. I was highly heartbroken by this. Skyrim, don't make me sad like that. Gutslit felt like murdering some Thalmor!

Go kill the ones at Northwatch Keep.

Start walking down the road.

Nothing I like more when I'm out on a walk than seeing the haughty, golden back of the last Thalmor in the line striding up the road as if they own it...
It's so satisfying taking them out one at a time, with the remaining members running around in furious confusion looking for me.

Just imagine this scenario except with an axe and helmets and insults flying...
