Ooooups. I might have just killed a crucian NPC, but i wanna be sure before i load from a long way ago.
There's this door, in the goblin caves of the Nether mountains, after the hall with the caged chest trap. One of the levers in in the rooms around that hall opens it; after it there's another door just like it, and i can't find a way to open it. Deekin spoke of some kobold, named Master Jumper, who's supposd to be the only person able to open the way to the dragon. Is that his door? No one answers when i "knock" it, so does that mean i accodently killed Jumper on my way there? Or is that not Jumper's door yet, and i'm supposed to open it using the levers?
Either of the northern levers closes the first door; is there some specific oorder in which i need to pull them so that the second will open withoutt he first closing? Or what? :=S

is there some specific oorder in which i need to pull them Without spoiling too much more, the answer to this question is 'yes'. Once you've puzzled that out, let us know if you still have a problem. It sounds you are going through this for the fisrt time so it's probably best if we don't tell you any more at this point (unless my answer does not solve your problem).

Cool!
Next question: is there someone, or something, within the game, that can give me a hint on this? Can Deekin be convinced to tell me?
The reason i don't wanna go trial-and-error on this is that in 3 of the 4 rooms, my gnomish self and my dwarven lady were shooting in from the door, provoking the sargeants to throw caltrops {or whatever those things are} at the doors' areas. So now getting in and out of each room is quite painful, aspecially if done repeatedly.
Which also brings me to a semi-related question: can caltrops {if that's what they are} be removed from an area in any way? I tried resting, and they're still there. Dorna doesn't see them as a trap, so she doesn't try doing anythng about them either. In real {non-computerized} D&D, you can pretty much just gather them without any effort, if you have the time and can see them... but then again, in D&D i never saw anyone using them as a granadelike weapon.

is there someone, or something, within the game, that can give me a hint on this? Once again, the answer is 'yes'. Look very carefully at the signs posted around that area and you should be able to work it out without having to resort to trial and error (which would be dumb - this is SoU, after all, which is cool, not the OC, which is less cool).

Thancue, it worked! :=D

Hooray. Have fun.
