Well, I found it! It was underwater! Instead of linking to the main pedestal, I used the link that looks like two triangles, back to back. I ended up in the water in the canal, I think. I found the slate, which still had the symbols on it for "rain". I had to erase that, put in the symbol that I saw on the pedestal when I originally arrived in Laki'ahn, and placed it down. The Bahro took it away, but I was still stuck in the canal with no way out. I blundered around in the water until I found the "hand" to link back to the main pedestal in Laki'ahn.
Is this the way it was supposed to work?
The answer is....chocolate! Who cares what the question is.....
