Raiders of the Black Ice
After spending a day of drifting down the Moonstone Stream, you traveled down the road until you reached Standing Stone Keep. "This is it, the limit of the Province of the White Sword, and the main line of defense against barbarian raiders."
The keep looks old. Older then any of the buildings in the rest of the province. An ancient guardian, who stood against untold foes and is ready to do so again. And to both sides, heading toward the mountain chain to the east, and the ocean to the west, you see a long line of tall monolith silently standing guard. "Those are the Lightning Stone," Charlotte explains. "They date back to the Califate of Nuat, and were built in case the dwarves ever made it this far north. Now, we're using the veil of lightning they can create to stop armies from passing through this plain."
As you pass near the keep, Drake waves at the guards on the wall, who return the gesture.
