The goblin warband had been working tirelessly to free the entrance to the tomb. The sappers continued to dig their tunnels to the south, eagerly cracking the inner walls from under the surface, even as the torrential flow crashed into them as they breached the reservoir.
Buried, drowned and left to soak, he remained imprisoned in his tomb for far too long. These wretched creatures attempting to free their idol only knew his existence through the oral histories passed down from short generation to generation. It was not until he mustered all his strength to speak through their shamans that their fervor was invoked, and now the hour of his liberation was at hand.
Once the basin drains and they breach the tomb, these pawns will become the first in his army. From there, the gathering of the horde must commence. The world that had forgotten his existence will remember that some beings should never be left to the past.
Hey all,
So when I did the Lakeside Ritual map I got an idea for this phased map and just had to do it. The idea being that your players need to swim down to the purple spheres of power and activate them to drain that portion of the lake. Eventually at the bottom they're able to access the double doors that lead down to who knows where.
Or alternatively the lake just drains at different times of the month or year and the spheres help unlock the door. Either way I hope you enjoy the map and it finds a home in your campaign! I'll be taking suggestions for the next vote as normal soon. :)
