@Storm:
Practically the instant a fleeing guest topples over and falls right on top of you making it quite obvious that something invisible is underneath him, two of the guards train their SMG's on your position and open fire. As fast as you can you weave astral threads of mana around yourself and start feeling the tug of your powerful levitate spell quickly lift you off the ground. The APDS rounds instead catch the guest who was left in your place and tear him to shreds. The shear amount of many you put into the spell catapults you through the skylight and out into the night.
The Valkyrie dematerializes and wryly informs you that she awaits your further orders.
@Everyone:
Brick's radar vision catches Storm flying through the window and out into the night. He quickly sends out the radio beacon and tells the team to prepare for extraction. Everyone gets up and starts running along the castle rooftops towards the rendezvous point and you can already hear the approach of the stealth chopper. In a hop skip and a jump your finally off on your way out of fairy-land and back home to the 'plex.
