Sarin -- if you would like to edit, then by all means do, but I think that you've answered Nova's question. If you want to expand on Zuromor's personal feelings, then feel free to add a new post and take the little party of Slave-Men out into the courtyard.
Dwarves -- You'll note you've just been presented with a plot twist. Feel free do deal with Lurg as you see fit, but please let him escape alive, as he
may be showing up again later. . .
EDIT -- The first version of the post had Lurg coming face to face with the Dwarves in the courtyard, but I've moved it to inside the Tower, as the Elves are still out in the courtyard and the Slaves will soon be out there too. For the moment, I think the Dwarves can handle the orc. After he gets away though, he will run through the courtyard, so if any of the Elves or Men wish to have a crack at him, let me know and get yourselves in position by the gate!
