I did a secondary skim through the forum, steel is confirmed to have been in the empire pre godswar and to have been entirely forgotten about afterwards, and before anyone says it, yes maidenscythe is steel as well, but its implied to have been based from meteoric iron during the peak of the empire, i don't imagine myself being able to convince savin to let a meteor fall from the skyYeah, I think your recolection of steel lore is accurate.
Anyway, if you do not mind me asking, do you have any pictures as a reference with how would you like your boyo to look?
as for direct image reference, not right now, I am a fan of the more lean body type, and given his to be profession he'd at least have some muscle, so expect those to remain consistent in his appearance
