Astrid will kidnap you from Apocrypha

When this happened to me I almost killed him he scared the hell out of me!

These guys are dedicated. Much respect. Wish there was an option to tip these brave bastards.

I had the man who starts Wyrmstooth come meet me at the bottom of Ustengrav two days ago

I have had him appear in Blackreach twice, and then he got stuck down there, and I had to go and let him out.

I had it happen in Frostroot Cave while it was still filled with bandits. He ran right past them to get my mail. Ever the professional.

Frostroot Cave is the entrance to where the CC Dwemer Home is.
