Yep, you've got it right; the barrier is part of a currently unimplemented quest. There's nothing else to do in the dungeon for the time being.

As for the Energy Crystal, the only thing you can do with it is click it in your inventory to get two high-end potions.

Huh. I tried that last night to no avail. But I'll try it again later on a fresh save (where I haven't entered Naradoth yet) and report back. Edit: All right, did some tests. I think I've solved this bad boy. (Tldr version in the last paragraph.) Test 1 - German, fresh save (a save where I've never ...

Heh. I had a hunch that that might be the case; that's why I made sure to include the vault number in the picture.

I haven't encountered this in Nehrim or, IIRC, Oblivion, but that sounds like something I've encountered before in a few other games - from more than one developer - when they tried to access sound files that were corrupt or which they couldn't find (not sure which).

As mentioned, there should be two tabs just under where the save/preview/submit buttons are on the left side of the window. Click the second one (it should say "Upload attachment" if it's in English), click the button immediately to the right of the first text box ("Browse..." in English), navigate ...
