I rush towards them, whipping balls of fire from my hands at the Mogs. I know it should never feel good to kill a living creature, but right now, it feels great. Now that I’m up Eight is teleporting all over the room, appearing in front of Mogs and slicing them to pieces with a sword. Nine is still fighting Setrákus Ra, but the two of them are moving so fast they’re just a blur. I need to get in there and fight, but I also need to stay here and help Sarah and Ella.

Suddenly, one of the Mogs advancing on me turns in a different direction. He’s not aiming his cannon at me. It’s pointed directly at Sarah and Ella, who are still lying motionless. He fires and their bodies start to convulse, and I begin to scream.

I watch in horror as Ella and Sarah’s prone bodies are hit with Mog cannon fire. John reaches them and I rush to his side. He’s kneeling next to them and holding their hands as their bodies shake. We’re too late.

After all of this, after we made it this far and we all found each other at last, it looks like we’re about to lose another member of the Garde. And Sarah. John just found her again, and he’s going to lose her. I close my eyes as well, bracing myself for another scar to burn itself into my leg, a scar for Ella. I know this one is going to hurt the most.

But nothing happens. Is there something different about Ella that her death won’t cause a scar? That can’t be. I open my eyes and look at John, who’s still hunched over Sarah and Ella, still intently squeezing their hands.

I look closer at the girls and can’t quite believe what I’m seeing. Their wounds – cannon blasts to their bodies and hideous burns on their faces  – are healing. ‘What’s happening? How are you doing this?’ I ask John, looking at him in wonder.

‘I have no idea,’ he says, shaking his head. ‘I didn’t know I could do this. I saw Sarah on the ground and I wasn’t going to let her die, or Ella. Not another one of the Garde. I won’t let that happen, especially now that we’re together. I took their hands and thought about how much I wanted their injuries to heal, how much I wished I could heal them . . . and it suddenly just started to happen.’

‘You’ve developed a new Legacy!’ I cry, squeezing his shoulders.
