Yeah, I missed it. Thanks. The trap is non-magical, it is just an effect of the colored glass and the lights. You figure that breaking a single crystal or vase will disrupt the effect and render it harmless. Among the papers and books scattered about the room you find six scrolls scribed at CL20: darkvision, greater magic weapon, hold person, lightning bolt, greater invisibility, and summon monster V. There is also a desk to be examined, but I'll need specific actions for it. And you find a concealed door behind a bookcase.
