Inside Brackwater, after discovering 3/4 dwarves, I reached a level with the dwarf Wethur, however, I cannot seem to reach the top of the waterfall, where the strongbox and supposedly the remaining 4th dwarf is. There are several passages which seem to deadend. With two of the interior passages, they seem to reverse and send one back into the area with plenty of cave lizards. Behind Wethur, there are some rocks which seem not too high, but I cannot jump over them. One cannot exit this area, because the passage that I came in on is now a reversing passage. It would be nice to accomplish this quest. Thanks in advance for any helpful advice.
