No, it the water outside the doors of Durin. You know, the water part of "The Watcher in the Water"?
Remember when I started making the lake/pond for the terrain? Well, this is (finally) the next step. The border was covered in a mix of sand, PVA glue, and water and left to dry. I purposefully wanted it a bit sloppy to give it a natural look. The brown rectangle outside the edge is just a scrap of cardboard I laid down to catch the drips. The few edges and corners of foamcore peeking out will be further obscured by flocking and paint. The center of the MDF board will get a water effect similar to my modular river pieces. Though the pond will be more a murky greenish shade. Once the water and the border are painted, I'll add a few bits of scrub brush on the edges and some grass flocking. The piece should be usable as water terrain for any scene, but should serve admirably for the tentacle fight at Moria's entrance.
