Five still can’t bring himself to look directly at Setrákus Ra, but his shoulders rise up and down rapidly, just like in the hallway with the Mog warriors. Inside his chest, a low rumble starts to build. It reminds me of a teakettle coming to a boil. I take a subtle step to the side, worried that Five might literally explode.

‘Enough of this inanity, children,’ Setrákus Ra says, but his latest rebuke is partly drowned out by the rabid scream that tears loose from Five’s lungs.

And then he charges.

At first, Five’s bare feet make slapping sounds across the metal deck. But as he nears Setrákus Ra, his footfalls become metal clanging against metal, his Externa changing his skin to match the floor. Setrákus Ra merely raises an eyebrow at Five, not impressed or intimidated in the least.

I don’t just stand around and watch. While Five charges in, I make a break for one of the nearby tool carts. If I can grab a wrench or any other object to charge with my Dreynen, maybe I can re-create yesterday’s lesson. Only this time, my target will be Setrákus Ra.

That plan, along with whatever Five intended to do, gets scrapped when Setrákus Ra sweeps his arm from side to side. A wave of telekinetic force blasts across us, knocking me completely off my feet and scattering the nearby tools to the far wall. His telekinesis is so powerful that some of the ships even rock to the side, their shocks grinding and creaking.

I land hard on my stomach and immediately roll over to reorient myself. Five was knocked into the air, too, but caught himself with his flight Legacy. He floats just a few yards from Setrákus Ra. Five’s skin is no longer the dull gray of the docking-bay floor. It has changed to a glistening chrome, like the ball bearing I know he carries around. So that must be jammed into his eye socket as well.

‘Stop at once,’ Setrákus Ra warns, but Five is way past the point of listening.

Five soars in towards Setrákus Ra, throwing big, looping punches with the intention of smashing his pretty human face. Setrákus Ra deflects the blows easily with his cane, although Five’s sheer animalistic fury is enough to drive Setrákus Ra back towards the open docking-bay doors.

Their scuffle opens up a path for me. Let these two crazies duke it out. All I have to do is make a break for it, dive into the open blue sky, and hope the Xitharis stone does what Five said.

Just when I start to make my move, I notice Setrákus Ra’s eyes flash. I feel an invisible field of energy pass over me, almost like the pressure in the room has changed. As he’s in the middle of throwing a punch, Five’s skin turns back to normal. His fist crunches against Setrákus Ra’s upraised cane. At the same moment, Five falls out of the air with a shout.

It’s just like at Dulce Base. Setrákus Ra has created some kind of field that cancels Legacies. He’s an Aeturnus like me, and now I know that Setrákus Ra and I also share Dreynen. His technique is different from anything I’ve been able to learn. It’s like he’s charged the molecules in the air around him, creating a radius where Legacies are useless.

Except it doesn’t work on me. I can still feel my Dreynen lurking within me, and I know that I could use my Aeturnus if I wanted. Somehow, I’m immune to Setrákus Ra’s version of Dreynen. Is it because we’re related? Or is one of my Legacies an immunity to Setrákus Ra? He said all that crap about our Legacies coming randomly and Lorien being nothing but chaos. But what if he’s wrong and my Legacies have been specifically chosen to destroy him? More important – does Setrákus Ra know that his power doesn’t affect me?

In that moment, Setrákus Ra isn’t paying me any attention at all. He’s completely focused on Five. I know I should make a break for it, but I find myself rooted in place. Even after everything he’s done, can I really leave Five behind?

Five is on his knees in front of Setrákus Ra, clutching his injured hand to his belly. Setrákus Ra’s unimposing human form has grown by a few feet – he’s taller and broader now, inflated in a way that is vaguely grotesque. He reaches down and palms Five’s head in one unnaturally large hand.

‘All you needed to do was follow orders,’ Setrákus Ra seethes at Five. He jerks Five’s head back so he can look him in the face. ‘We could have walked into the Sanctuary together, if you’d only brought me that damned pendant. And now, this – you dare raise a hand against your Beloved Leader. You disgust me, boy.’

I don’t know what Setrákus Ra means by Sanctuary, but I make a mental note of it. I also take a step towards him and Five, still torn between fleeing and helping, and uncertain of what I could even do in a fight against the Mogadorian ruler.

Five’s head is cocked at an awkward angle, so he can only gurgle in response to Setrákus Ra’s ranting.

‘I should have known that no member of the Garde could truly be salvaged,’ Setrákus Ra continues. ‘You are my greatest failure, Five. But you will be my last.’

Five cries out as Ra’s hand tightens on his skull. My stomach turns over as I realize he’s literally going to crush Five’s head. I can’t let that happen.

With all the telekinetic force I can muster, I shove Setrákus Ra towards the open docking-bay doors.

His eyes widen in surprise as he stumbles backwards, the open air tugging at his fancy suit, which is now bulging at the seams from his inhuman growth spurt. Setrákus Ra loses his grip on Five’s head, his nails scratching divots into his scalp. He manages to stop himself before I push him off the Anubis, and I can feel his telekinesis battle back against mine.
