Once there are finally no further distractions you get a look at this hallway, which leads west:
You're standing in a 10(long)x20(wide)x10'(high) area with a 5x20x10' pit filled with goblin swords, spears and morning stars, rusty tips up.
The other side of that easily jumpable DC10 gap, the hall continues 50x20x10 completely silver. Fun fact: silver has a bit of a rainbow sheen to it...
At the end of that section is another pit just like the one previously described, although from here you can't see the swords, so maybe there's something else down there.
And then there's the 10x20x10 end of the hallway which is not shiny, appears safe, and has the door to the next room. Good luck.
