You are Grey Worm (Beaver)!
“Games are for children.”
What do you call the toughest warrior of the toughest army with the toughest backstory? So what if you’re not the greatest joke-teller, or that you don’t like to drink unless commanded to? You’ve experienced some of the worst that humanity has to offer and, not only survived to not tell the tale, but are currently kicking the worst’s ass. A true Beaver, you prefer to do your duty without the attention that gaudier types might seek. I would call you a humble survivor, but even that might be too much gilding the lily for you.
