Riften don't play but don't underestimate Dawnstar.
Took a long break (in Skyrim terms anyway) from the game and just started a new build the other night. The unthinkable happened and the guards and people of Dawnstar saved my ass.
So I'm on my way to the College and I decide to stop by Dawnstar to hit the iron mine and the merchant chest on the way and all is well but when I left the mine I started scanning for Dragons since they seem to spawn quite frequently when I come out, but again all was well. I hit the merchant chest, grabbed some goodies and a few enchanted items that I was planning on disenchanting in the White Hall. So I go in to the White Hall, steal some Ice Wraith Teeth, do my disenchanting and exit. Before I can start scanning for dragons I notice Mirrak's Cultists walking up the path towards me. I get scared since I am totally ill equipped to handle these guys at this point and run back into the White Hall like a coward. Regroup and decide to exit, I drop a Rune and start running before they have a chance to open dialogue. So far so good only I hear a civilian say "Somebody do something!"... which always means vampires in my experience and sure enough, vampire ambush. Lucky for me the Kahjit(?) had set up shop at Dawnstar and was keeping them busy, especially since TWO dragons decided to attack afterall. By the time the Dragons appeared the Cultists had walked into my Rune and were fully hostile. Long story short it was complete bedlam for about 10 minutes and all I really had to do was stand and shoot poison arrows in every direction imaginable. The merchants, guards, miners and civilians did all the dirty work.
After that I began wondering why I took a break from this game...
