Possibly my oldest character concept-- I developed this character in elementary school and have been building and changing him since. To be perfectly honest, his original inspiration is Ashitaka from Studio Ghibli's "Princess Mononoke."
Maybe it's not the most original thief outfit, but I made it based on who he is.
Isaac has a lot of stories-- like I said, he's been in development for a decade and a half. That being said, here's his story within the GW2 universe:
Son to a merchant and a royal guard, Isaac lost his family when his father contracted a strange illness that caused him to slaughter his family in their sleep. Isaac, more of a night-owl, managed to escape with his life. Within the week, Isaac returned to kill his father.
Since then, Isaac has become a wanderer, investing his time and resources in making allies across Tyria. Along the way, he gained a reverence for the Pale Tree, seeing it as the only incorruptible good in the world.
Until, of course, Mordremoth awoke and the Pale Tree's secrecy and deceptive nature was revealed. Isaac lost his faith in her.
After Mordremoth's fall, Isaac sought some kind of peace in his life. He turned to the Kodan, hoping to find balance. He has grown immensely as a person, and is ready to protect his allies once again.
