Yeah really. Also ran into a fuckin sabre tooth tiger. C'mon man!
I've been in Windhelm but I'm not sure how to start the Dark Brotherhood quests. Someone wanna spill the beans? Haven't been to Riften though, too busy hunting dragons and raiding fortresses.
Go to Windhelm and speak to the locals, go to Aventus Avintinos home, talk to him, go to Riften kill Grelod. Eventually you'll get a note off a courier saying 'We know'. Sleep (I slept in Riverwood, dunno if it matters, when you awake you're in some shack and get to do a great little thing (Three hooded guys and you choose who to execute)
I just got the greatest glitch ever. I was talking to Savos Aren, the arch mage, and I accidentally tapped the dragon shout button and I froze him, and he fell over and I hit the convo button again and he was still able to talk on the ground, then when he got up, his legs got glitched up in a basket and he was walking with it around him.
