Eternal

Cyrus and Talia are still Eternals and you have to believe that despite whatever divine indoctrination has taken place that they still have some sort of loyalty to the Emperor and not the Shadow Guard and certainly not Dendrin.

In any case, you’re going to try to get through to them and you don’t know how to do that except just by being direct.

“Do you two really think Dendrin is more powerful than the Emperor?” you ask.
“Of course! How could he not be? Why would you even ask such a thing?” Cyrus says.
“Dendrin showed us…all of us that the Emperor and the Empire is a lie and corrupt! He is the only true path! You were in his presence! How can you doubt him?” Talia adds.

“I might ask you two how you can you suddenly revere Dendrin and turn your back on all of what has been taught us? Dendrin…whatever he is obviously is going to show us, or tell us whatever he wants for his own purposes, that doesn’t make it true! We’re Eternals first remember? We swore to serve the Empire, it’s why we were born!”
“Stop it! Just stop! You’re speaking heresy and foolishness! I think your mind was too weak to withstand the greatness of Dendrin and has been damaged!” Talia says.
“On the contrary I would ask how is it that I have maintained MY ability to question the Shadow Guard agenda? Why is it that Dendrin did not just destroy me if I wasn’t worthy? Perhaps I’m the strong one. I managed to hold on to my beliefs against a god while you two quickly abandoned them completely. Now you’ve got two options, you can either leave this place with me and we shall report this treasonous organization to the Empire and I swear I will not mention your own doubts in the Emperor.”
“The only reporting you should be doing is to either Brother Gray or Master Ebon about your sickness and hope they know how to treat it! I’m warning you, continue to speak the way you have been or…”
“Or else what Cyrus? You’ll kill me?” you ask and shake your head. “Do what you must then, but see now that I will not be able to get through to you. Now what about you Talia? Are you completely…”

Before you can complete the sentence, Cyrus attacks you. You narrowly miss a blade to your chest and throw Cyrus face first into a nearby bed. You then follow up with a stomp to his spine though you fail to break it and instead he just grunts in pain. You pull out your own sword and then that’s when Cyrus starts using his new shadow powers. He rolls out of the way and turns invisible.

You begin swinging at his closest location, but he slips by and stabs you in the foot. You wince at this pain and kick forward with your other foot. I lands somewhere into Cyrus, because he makes another sound. At this point he’s flickering in and out and also breathing heavy. His inexperience at the shadow magic has reared its ugly head again to your advantage.

Unfortunately you were so focused on fighting Cyrus that you completely forgot about Talia, she however hasn’t forgotten about you. You feel two daggers go excruciatingly into your back and puncture your vital organs. You yell out in pain and collapse on to the floor.

“(Wheeze) Thank you my sister. (Pant) Only a shadow for a little while and we’ve already managed to kill an enemy of Dendrin! I’m sure someone heard our fighting, but I’m going to go find Brother Gray, you stay here and watch his body, though I imagine he won’t give you anymore trouble.” Cyrus says and leaves.

You aren’t dead yet, but you soon will be. Talia, stands far enough away from you so you can’t do anything sudden to her in your last moments.

“Why did you have to say anything? Why didn’t you just submit to the will of Dendrin? You made me kill you!” Talia says with a tone of regret in her voice.
“No I didn’t…I did my duty. You chose to abandon yours…”
“I didn’t! I…”

Talia’s voice quivers a bit, like she’s genuinely upset about having to kill you. You didn’t expect that, maybe it will cause her to question her priorities now. Perhaps your actions here have accomplish something after all and the seed of chaos has been planted to destroy the Shadow Guard from the inside before they can carry out whatever plans to betray the Empire.

You comfort yourself with these thoughts as you pass from this world.
