I think Endemerrin is one of the more unique characters I've ever played. He has this one major strength, that also happens to be his biggest and more dangerous flaw of all, which has been an interesting thing to run with. He's missing his left arm, and has a Magitek Prosthetic in it's place. Great in theory. It's strong, it doesn't bleed, it has a myriad of uses that a normal arm doesn't...  ...but because he has this idea that "Hey, I can do more with this than a normal arm", it has lead to it being broken, battered, and even flat out destroyed on a few occasions (which isn't all that good for his health for a few reasons.). He's got this great strength, but at his core he's quite literally handicapped. For the longest part of his development he was absolutely ashamed of his situation as well. The way Eorzeans saw Magitek and Garleans made him feel like he was some sort of monster. The thing that they all hated. Went to great, great lengths to conceal it. Wasn't until he met certain people that he started to come to accept himself for what he was.
I was a Hyur in 1.0, and my character was Garlean (Technically not an Imperial~) at one point. However, I made the choice to retcon into Miqo'te in ARR and that has put an even greater spin on things, as we've seen that while Imperial society does have mixed races, pureblood Garleans (I.E Hyur) are favored. Makes me feel as though his fleeing Garlemald has that much deeper of an impact on his character. There's a few other spins on him that I don't really delve into outside of actual roleplay because there's no fun in just spilling everything about your character to everyone (in my opinion, anyways.), but those are just a few of the things that I feel makes him a fun and interesting character to play.
