Grabbing the lightest sword she can find, Eshi turns the blade in her hands and skirts away from the broken window to wait for her moment to strike back.  The distortion of the air in the room below is beyond her immediate notice, but she starts when she sees a man-- no, a demonic beast of some sort-- approaching from below.  She curses-- she's left with no escape, if the goat-legged man intends her harm-- she presses to the edge of the stairwell and holds her attack, waiting for him to identify himself by word or action.  ((sense motive: result 16))
