Rhemic Empire (2)

I'm leaning towards something like this. The guy with the bow has a range of 20, but his evasion and speed are low, so it's better for him to cover the hall from this balcony and avoid close combat.
Revan said that we'll have to search the guests, so let those two NPCs do it – they go in with the guy, search, and come back out. Just in case there's a continuous stream of guests, they can stay in the rooms marked in green.
I, personally, am taking a risk by being in this position, but from here, I can sprint into any of the rooms or the left corridor, and at the same time, I'll keep an eye on things to make sure no one sneaks through to the left or from G while the searchers are in their rooms.
I'm not sure about Nebos, so we need his opinion. If you really want him to sit in the attic in stealth, that's fine, but then either he sits with the archer as a pair (is that effective?), or we need to move him somewhere else. I'm just worried about putting him in a vulnerable position, so I think it's better to leave him in the hall, at least. Maybe somewhere in the center, higher up, on the central M?
And then, if some aggressive enemies break in, the three of us will have to retreat to the hall immediately, where you can then cover us. I'm a little unsure about this, but I don't think there are any other options.
