Three Clues - Who Am I?

[Rath Darkblade]

NBS ... nope.

Tawmis ... hmmmmmmmmm, nope.

[notbobsmith]

Are you in the mountains?

[Rath Darkblade]

Not always, no.

[notbobsmith]

Not alive. Not natural. Are you man made?

[Rath Darkblade]

I am indeed!

[notbobsmith]

Original clue:

I am earthy and glassy and nourishing;
none can be as versatile as I.
Do the right thing and I will be flourishing;
Do the wrong thing and it is bye-bye!

Not exactly in the desert. Not always in the mountains.

Are you the City of Raseir itself? "Do the right thing and I will be flourishing" Restore the fountain with the water elemental and the city is restored. "Do the wrong thing" and the city is destroyed by Iblis.

[Rath Darkblade]

No, I am not Raseir.

Would you like a clue?

[notbobsmith]

No, I am not Raseir.

Would you like a clue?

Well, I did make a guess, so we get another clue.

[Rath Darkblade]

Hmm. Let me think - ah! Here's a clue:

I do not usually appear
unless you make a blunder here.

Hope that helps!

[notbobsmith]

Are you a death message?

[Rath Darkblade]

Nope!

[notbobsmith]

Are you the broken screen when you try to throw something at Julanar?

[Rath Darkblade]

Yes! (How did you know? Just wondering)

[notbobsmith]

Yes! (How did you know? Just wondering)

The "sort of in the desert / sort of in the mountains" along with "only appearing after a blunder" made me think of something like a death screen. I think "glassy" from the original clue is what made me finally think of it.

My turn:

You can not see me
And you don't really need me
But look to find me

[Rath Darkblade]

Are you in a game with the word "quest" in it?
