Redhawk Caldera By any other name.

"Not all lakes have fish," Somnia started, preparing to explain, "Once this was a volcano. Then the top came off and left a huge dent in the ground; the lake without water. It became a lake from the rain filling it in faster than the rainwater could evaporate. So it's pretty much a giant puddle. How would fish get into it if there are no rivers or streams connecting to it? Well, I suppose that when it rains a lot it could overflow and create it's own streams, but it would have to be a real bad flood for fish to be able to swim up the caldera and into the lake." Whew... A little sidetracked about one way fish could be in it, but it still worked.

Now that she thought back to it, Fitz probably wasn't looking for an explanation, just a yes or no. Somnia often took explaining things to an extreme, while others just stared at her, trying to make sense of it all.
