Katherine Summers

It's important you know the truth, Katie.

It's important you understand how your mother and I arrived in this situation, in case we don't make it back. I need to be sure you and future generations understand what really happened: the truth about the day they celebrate as a holiday and the true cost of our failure.

We called ourselves "heroes" but we behaved as anything but.

They'll tell you it was unavoidable, even if the mutants had been there to help. It was not unavoidable, Katie. We brought it on ourselves. At a point in time when I was entrusted to ensure unity, we were anything but unified and I owe it to my comrades to continue looking for a solution. Should your mother and I fail in our mission, they will kill us. They'll tell you lies. They'll tell you there is no hope. My dear daughter, if you remember nothing else that I've taught you, remember this: there is always hope.

If you're reading this, Katie, you've made it to your sixteenth birthday. For that much, I'm grateful. I know Hank raised you well. He's a good man, the only other soul who didn't give up on humanity. He delivered you into this world, and as your godfather, I knew he would see you through it. It was Hank who diagnosed you as human; Hank who forced us to realize that you'd never be safe here and that Eimin's forces would never stop hunting you should your existence be discovered. That's only one of the reasons we've continued our struggle unto this. I can't abide my failure to unite man and mutant. Can't abide what that led to. When unity was most needed, we were divided. I was the one responsible for bringing them together and I was the one who failed the earth.

I'm more sorry than you'll ever know that we couldn't be there to raise you. Please know it's our love for you that fuels this struggle. Looking into your eyes -- the same color as my mother's -- it give me the resolve to fight a world determined to forget the past. Eimin has rewritten history, convinced Scott and his X-Men that the day of Armageddon was inevitable. That all the blame lies with Thor, the Avengers, and with me. She's convinced everyone to accept the death of humanity. Don't judge them. They weren't there to see the truth, but your mother was. She watched it happen and it was avoidable, had the mutants been there to help.

Once they work out what we mean to do, they'll go at any lengths to stop us but what we set out to do, it is the right thing. To risk leaving you without your parents, we don't take this lightly, my beautiful girl. But there is too much at stake for us to be selfish. That's the meaning of being a hero: doing the hard thing when it's right.

In order to undo my failure and save the world, I have to destroy Planet X.
