"Come now, I'm sure we can go peacefully," says Gregory, bull****ting for all he's worth and laying his quarterstaff- his only visible weapon- on the ground. "I mean, it's not like we could get far." He nods respectfully to the guard, his mind racing. "I would offer you some advice though, for the next set of travelers that comes by here." Without waiting for an answer, he walks to beside the captain and strikes a pose imitative of him.
"Now say some nice, strong bunch of folks turns up- they look like they could do a lot of work, but also look like they could cause you some trouble if they had a mind to it." He bows to his fellow travelers, offering them a clandestine wink on the way up. "Now I'm just a simple wizard, but I'd say it'd be much better if you got them in the gates first. So what you do is..." at this point he switches to a deep booming voice. "... Good day, fine travelers! Welcome to Sinistra. Come on in for food, a nice bed, etc. etc." He stepped back to where he once was and turned around, his voice normal again. "Bless you good sir! I'll just walk into the gate now, with my back turned to you." He matched his actions with words, walking towards the gates then turns and imitates the guard captain again. "Come right in! I'll just follow you, shall I?" He turns back to the guard. "And
that’s when you get the drop on them, like
this," he says, and dives for the horn.
ooc: Since I could be interrupted at any time during this bit, anybody doing something else before I finish prevents whatever after it from happening. Like if the guard wants to smack me for my insolence, for instance.

Anyway,
if it goes as above, intiative (13+1=14), with my frantic BSing (bluff check, if needed, 17+10=27. w00t.) hopefully gaining a surprise round. He makes a grab for the horn, rolling a wopping (8+0=8) on the disarm roll. Maybe this wasn't such a good idea after all....
And as a last note- this is my first time playing by post in a while, so if I've violated any

etiquitte grossly (rolling my own dice, what have you), call me on it.
