I am playing Shadowlords and it's pretty good, but I am stuck at one part. I am in module 2, under the temple, at the part with the three levers. It is obvious to me that I must use the King and Rook pieces to teleport myself around after pulling the levers, but since I trade places with whoever holds the companion piece to the one I have, I need to be able to give it to someone who will stand by the levers. I am with Anera and want to give her a piece, but cannot do so. I cannot access her inventory and see no other way to give it to her.
Any suggestions?

its been a while...
but you can put one piece into a barrel or something near the door i think and then teleport to it

Thats right. That is the trick to getting in. Took me a long while to figure that out ;)
