I'm trying to do that glass key quest thing, with that vault in the zoological building. This is the order I did everything. 1. I found that book in the locked glass container in that womans house whos husband died in Caladan. 2. I made a glass key out of that schematic with the heart stone and mithril ore. 3 I opened the vault with the glass key and took those key things out of it. 4. I went inside the place of lost voices and put the keys in the machine. 5. I went to the secret entrance to the iron clan. Now what? I seem to be stuck there is some kind of pedistal and an iron circle thing next to a mountain. What am i supposed to do here?
The key you made was iron, not glass. The true glass key needed for opening Iron Clan is in the Panarii temple in Caladon, but you won't get it until you solve the Saint Mannox quest (probably the most irritating quest in the game).
