This underdark map section extends the border of the Lake of Spires and reveals a few more rock formations breaking through the surface of the water. While these parts might seem a little boring they are just as needed for a complete map and campaign setting, this gives your adventuring group something to travel through, a place where wandering encounters, ambushes and the unexpected can thrive. In my campaign these locations will be where my adventures get their first introduction to the sahuagin and learn 4 valuable lessons, there is no such thing as a safe place and the drow are not the only enemy.
