Again
Hmm, magical ape, yes, I suppose a magical ape would be considered 'magical' and could hit creatures you need a +1 or better weapon to hit. And better a panda bear than a koala bear, yes? (I probably should go and make sure there are twelve different such bears to be had.)
The rusty key, like all the other keys you have collected here, is magical. The dancing statue also radiates. None of the other objects you mentioned seem to be magical. The magical ape would radiate magic if he were here, which he isn't though.
Okay, it sounds like you are returning to the junklands, and heading back towards the chapel. If you'd like to do anything before this, just post it and we can retroactively fit it in.
You head back through the rusty door and make your way through the wasteland towards the chapel. Things are as they were before; there is no sign of the warrior outside.
You enter the doors. Inside, however, things seem rather different. All the scrap metal within the chapel itself has been organized, and in the center of the room, it seems that a short, wide metal tower has been, or is being, constructed. It stands about sixteen feet tall at peak, and is made out of a strange collection of metal objects and weapons. The other objects throughout the room have also been organized into piles. The armored figure has been busy, it seems, and indeed, you see him lugging a large piece of ribar across the room. Your presence, however, disturbs his work. He draws his sword, fires it up, and re-engages.
Go.
