Junkboxes Needed

My rogues need to hone their lockpicking skills, and I need locks of adequate difficulty -- the stuff Zan makes us is unfit for all but the lowliest neophytes. Tell ya what, if you bring me 5 Heavy Junkboxes, I'll put in a good word for you around here. You can unlock the boxes and rifle through them, but you'll have to leave at least a few coins in them... even a rogue in training needs motivation.
