EDIT: Fixed the anatomy. Don't want to spend more time on it.
Prince of Patiala lol. I could't think of anything better. I was going to go with King of Khalistan but that word has many political undertones and is either hated or adored depending on who you talk to.
So help me out with the title guys.
This was obviously inspired by Prince of Persia.
Background: This left arm is ethereal which means it celestial, immaterial and not of this realm. Prince was handicapped by warfare, and this was given to him by a group of priests. They performed a ritual to build it. With this arm, Prince can do several cool things, one of which is to summon that shield he seems to be wearing.
Although the arm is ethereal it can certainly interact with the physical world... well otherwise it would be useless!
