As you are milling around, a youngish-appearing (Perhaps 200?) Elven lady steps through the far door, instantly gaining all your attention. Her voice is easily heard through the sudden silence, though she speaks softly to the guard. "It appears our guests have arrived. Master William would like them escorted up now." She then turns to you and bows, before turning and disapearing back into the doorway.
The Guard motions towards the Doorway and speaks in a deep voice. "This way, please." He then takes up Guard at the door again once you have all passed through, and closes the door behind you. There you find a sprial staircase leading upwards into the tower. Following it for at least a full minute, you finally exit into a large room filled almost to overflowing with laboratory equipment, beakers, vials, potions, and books. One corner is set aside with several chairs and a single Crystal ball. In front of it sits the old man, whom you assume can only be William, seemingly in a trance, staring deeply into the ball.
Beside him stands the Elven lady, who motions for you to enter the room. "Be seated if you wish, or browse the bookshelves if it so pleases you. Master William will be done his divining in a moment." she says again in a soft, though easy to hear tone.
EDIT: Incontinuity error fixed.
