Number 6 in the sea-shore underdark set - maybe the last in the set? Maybe one more.... then I'll start doing some non-seashore based ones.
This is a quick one, but a big one on paper (full sheet map). It's a bridge over a river that feeds into the sea, the bridge top is about 50 feet above the river, so the bottom is probably about 40 feet above. There is a little guard tower onthe upper ledge, 20 feet above the ledge and bridge (60 feet above the water level).
The location is nice for use in game as a way-point because it is memorable (bridge, river, guardpost, long old worn down stairs to the seashore), and it acts as an intersection, with three egresses into the underdark proper from here, as well as access to the sea and to a minor shipping waterway.
I didn't like this one much when it was about 2/3 done, but now when I look at it, it's one of my faves in the set. Definitely got the feel across a lot better than the dwarven stair.
