OOC:
The party is ready to enter the depth of the ruins, with the dwarf playing seeing eye dog to the humans, and eventually the elves when no light will enter the ruins by the looks of things...
About 9 meters from the entrance, everyone can see a door on the eastern wall. Then only the elves and dwarves will be able to see past this point, another door on the western wall this time, about 5 meters from the first one (14 meters from the entrance total), Then the entrance to what looks to be a corridor on the western wall, another 5 meters further (19 from the entrance), a larger entrance of a corridor on the eastern well this time another 4 meters further (23 from the entrance), and finally what looks like a collapsed stairwell a few meters after that...
