Hello everybody
With the lobby cleared I turned my attention to the dining hall next.
There are at least 5 guards in there, so I got them to come out and investigate by throwing bottles and making noise by striking things with my sword. While doing this and then reaching up to the big light fixture I was able to watch them come out. At one point a guard came from the other direction and I had to be quick not to be seen.
Once there was only 2 guards left I went inside the dining hall and from the top of the wall above the elite guard I linked them both together and used a sleep arrow to put them to sleep.
Thanks for watching
