Search the stairs once the door is unlocked to disarm a trap. If you do not disarm it you will be dealt up to 1500 damage points. Climb up.

You are now in Movario's study room. Do not take anything from the treasure box; it is a trap, and you will be hit for 500 life points. Searching the treasure reveals it to be fake, so don't bother. Search the desk to obtain Movario's notes (volume 1). Read the notes. Pick up the waste-paper basket next to the desk and search it to find a ruby key. Search the bookcase to the west of the trash can, and use the ruby key on it. A set of steps will rise in the north-west corner of the room.

Climb up the staircase. If you need to boost your Thieving level again, do so now. Search the bed to remove the covers, revealing a hidden chest. Search the bed again to dismantle the bed-chest trap and finally use the ruby key on the chest. Open and search the chest to obtain a strange key loop, strange key teeth, and Movario's notes (volume 2). Read these notes too.

Do not drop either of the sets of notes after reading; you will need to show them to Thaerisk later.

Now that you have plundered Movario's base, you need to leave the area with the obtained items. When you attempt to leave by conventional methods, you find that a magical force is blocking your teleportation matrix. Therefore, you must now find another way out.
