The Unknown Lands
After descending the stairs you enter a large, well-lit stone chamber. A large set of double doors is set in the wall ahead of you, solid steel and with rings set into them. Writing that you can’t decipher is inscribed along the circumference of the chamber.
Found in the Dead Mire, the Lightvault is an underground vault beneath the ruins of a temple to an unknown god. The vault is fill filled with carvings of spear-wielding soldiers and sun motifs. Several traps and puzzles based around directing a beam of light have barred the party’s way.
