Miscellaneous: Dragon Necropolis: Green fog?

[Danth]

On P1999 DN has no zone 'fog' inside it. I noticed in an old classic-era screenshot on the wayback machine that DN may have potentially had a greenish background fog, similar to Kithicor or the Faydark zones. I'll provide a cut-and-paste link to the screenshot in question. It's been far too long since the classic era (and I spent far too little time in DN) for me to have any personal memory of this specific issue one way or the other. Opinions?

Here' the shot in question; it's from the archived 2001-era dragon construct allakhazam page.
