Lynrae has made her home underground on the landmass across the water from the public fort.
I found a rich cave near there, we've taken a ton of iron out of it.
I tried out a neat trap design I found on the wiki, it uses a preasure plate to release a lava flo. I've got a non-lethal water version set up in the experiment courtyard of my castle. It exploits a technical quirk of how liquids calculate where to flow. link
I need a new building project...I kinda want to make a small town. several buildings, roads, yards etc.
