I should point out to the people whose characters recognize Maryev for his race might not be able to pinpoint it exactly because he's in full armour and his face is concealed within a helm, so he should just look like an abnormally large man to most people. 

Certainly not saying there aren't people who wouldn't immediately have him pegged as one based on physique alone, but they'd probably have had seen one before/ been well educated about the various races to identify traits. 

Anyways! Minor detail, just thought I'd clarify just in case you guys were like "I SEE YOU JAKE SULLY!" because of an impression his face isn't concealed. He learned that lesson hard his first couple of weeks in exile; people tend not to like monsters all that much. :D
