Based on the description you got, the guy with the sword is Steel Talon, the swords master that escaped Blackmist. The boys downstairs are just common thugs, and the bound man is probably the same. Whoever he is working for was cheap on this mission except for that sword and its wielder, the thugs aren't even Extra.
Your strikes on the mans wrist hit with surgical precision and he drops the sword. The second it leaves his hand the blue light leaves the blade and it splits into its component pieces which scatter across the roof. The man laughs and looks at you in surprise, "Your first strike and you find the prototypes fatal flaw, impressive. Even more impressive is that you were able to disarm me
, a feat none has been able to accomplish in a decade and a half. Lets see if you can do it again." He pulls what appears to be a cell phone from his pocket that is actually a disguised blade like the first. He shifts into a defensive stance and looks at you expectantly.
Talking is a free action if you would still like to go.
