OOC: Unless we are in a combat situation, I'm going to declare that anyone who doesn't post by the time of my last post on the next working day, isn't doing anything.
You proceed the rest of the way to the tower. The tower is clearly a defensive position. There are no windows large enough for anyone to enter or exit through, only a few arrow slits here and there. There is only one entrance that you can see and that is a door at the top of a flight of stairs.
The river flows on the other side of the tower, tumbling down off the edge of a gorge. Amaryllis, you can't see the waterfall from where you are. Do you wish to go and investigate? From the sound of the water, it is a long way down.
Namfoodle you notice that the tower is of excellent Dwarven construction and would likely extend down as well as up. Given that it appears to be a single defensive outpost and from the angle of the walls, you doubt that the distance below ground is all that much greater than the distance above ground.
Anyone who happens to be looking at the dwarves rather than the waterfall's rather pretty rainbows or the tower's superior stonework, will notice that there are in fact 4 dwarves standing around. They are wearing chain shirts, baggy clothes, with dwarven battle-axes tucked into their belts or slung over their shoulders on straps. There are also 5 dwarven bodies lying on the ground. Those of you who were examining the tower would have noticed that there are a number of crossbows near the steps leading up to the door. There is also a hairy, dead creature on the steps by the front door.
