I use my own world of Everbee. Right now we are in the Isian area which is mostly underground--so, my version of the Underdark.
I have areas (Lamothe) where things are very gothic and areas (Naphtali) where things are very Indian. Chrysi where it's Roman, Maighdine and Lyonaighe where it's...

I personally would ignore the "rules" and instead rule that if you wear this...
Magitech and the demystification of magic.
The nuance between warforged and robots is thin, and apparently was missed by the producer in some people's estimation. I suspect that some will find it perplexing that some of us are uncomfortable with robots but not warforged.
The personality traits etc. already have guidelines for applying alignment to those traits. I think it was in the Ideals. I really miss the Personality Traits etc. and I wish they would have been included in the 50th Anniversary edition.
