I think we should consider renaming these guys.
Without modifications, Infernos are the most 'human' looking of the Radakan races, ...
Infernos were perhaps the first specie to realize the work of the gods, and decided that their disease is a gift given to them, allowing strive to turn their bodies and homes into celebrations of holy wisdom.
I'm thinking about adding some motivation for them to leave their communities, possibly as engineers in trade for rare materials, to prove themselves, or to escape the guild society
I really feel that a 'hot headed' race is unrealistic and should be confined to individuals. I think the above addendum is much more plausible given the alterations to their culture, while still leaving open the idea of the quick-to-temper Inferno.
Due to their culture, Infernos has become very adept at surgery and mechanics. Although they are not gifted with great accuracy, (accuracy of what?) their engineering aptitude is to be celebrated.
Your additions and improvements look very good!
Differentiating members of a single race is fine, but the differences should be very simple. (E.g. house styles differ in hot and cold regions.) It's nice to have detail, but we shouldn't overcomplicate things. Our players will only get confused.
How would they look like without modifications? Not exactely as humans, I hope.
I thought you wanted to scrap the disease idea.
It's a good idea. From a game design standpoint, mixing races can result in very interesting situations.
I think the original writer meant dexterity (hand-eye coordination).
