Perception Check.
You find nothing more of importance without checking the tombs. The doors, save for the one that Nadarr is at ((since he's in your way)), are locked.
Karl looks at Nadarr and can't help but smirk as he sees the glint of gold in front of him. "Leave it to Nadarr to find gold, even in the middle of a graveyard. What does the plaque say, Thoradin?"
((I can't remember if Nadarr related the return the bones subquest, or if Karl was conscious enough to appreciate it.))
The plaque is in common, dwarven and several other languages and is larger then the other plaques. It reads clearly in several languages:
Here lies Dastot Uristash, Toady One, founder of the settlement Uristash. May his soul find peace without his bones(?) This door, doesn't seem locked. Nadarr opens it. Inside is a massive tomb that has a ceiling higher then the mass gave behind you, fully engraved walls and floor. Magma seems to flow through a barrier of steel bars with a large vat of water streaming next to it but not touching the magma. The room, surprisingly, is cool, despite magma flowing through the floors under a thick layer of glass, iron and 2ft of of space, making the magma light the room, but staying a fair distance away. In between the magma and above the water flows, is a giant engraving of a humanoid with several ones underneath kneeling before a proud humanoid raising a pickaxe that points to the large figure. And the entire room is plastered with silver and gold lining on the engravings, making the entire room appear as if it was blinding with the light from the magma and braziers of steel and a shiny metal you assume to be platinum. Dwarven runes are marked all over the light sources and they appear to be lit without the use of fuel. But what sparks your eye is in the center is a coffin with a plaque in front of it with dwarven runes... And the coffin is solid platinum with gold trimming and plastered with jewels that starts to make your mouth water. Just the coffin lid alone would make you wealthier then most kings with the sheer amount of gems put on it that are altered in a way so they resemble the same engraving on the back wall. As you step into the room, you feel as if you are in the presence of a god.
