"The name of the island they found me on is Lian Yu. It's Mandarin for purgatory. Now I understand why. The memories, the pain, I've never escaped them. They're always with me, a reminder of what I had to endure with only one thought, one goal-- survive. To save the multiverse, I must become something else. To do that, I have to return to where my journey began-- purgatory."
Oliver Queen
