Now these two NPCs played not nearly as important a role in the Cloudsdale Chapter of our pen and paper RPG as I (then as the game master) had foreseen and maybe that’s why I am too lazy to vectorize this sketch which I used back then (in early 2017) to give the players an idea of what these two pegasi (wings not visible in these frontviews and with their armor) looked like.  
Can you guess which of the two is the good guy and who is a traitor? ;)
 
In fact the friendly looking Corporal Copperhead on the left side turned out to be working as an agent for the organization our group was working against. I like telling names, but luckily nobody else in our group was so much into US history to interpret the name “Copperhead” as anything but a reference to the Copper helmet he was wearing.  
Sergeant Swiftstreaks on the right side may look grim, but got his heart in the right spot and is a dutiful pegasus guard of Cloudsdale all the way.  
As mentioned above, these two didn’t play as large a role in the Cloudsdale chapter as they could have. At several decision points the players in the group decided in ways that led them away from closer contacts with “officials” of Cloudsdale and the guards.  
Nevertheless these two were the first pegasi our group met after the dark cloud near Cloudsdale.  
Funnily enough, one player in our group who is the least ready to share information with strangers not just immediately bawled at Sergeant Swiftstreaks in such a way that it prevented the beginning of any constructive relationship, but the same character also ended up liking Corporal Copperhead and being more ready to share information about the players’ actions with him than he was with most other NPCs. It was a relief though that this player got suspicious only just in time before he could spill the beans about two things that would have really messed up things for our group big time.
