I am not going to lie; I did not think anything when I initially encountered Phainon in the Amphoreus arc. I thought it was just another overpowered hero HoYoverse threw at us. Slick style, glittering fighting effects, the commonplace.

Then Version 3.4 fell, and all of a sudden I’m sitting there at 2 AM reading theory threads since there is nothing about this guy, what it appears to be.

And now, this is what I got when I actually listened to the story.

The Name That Changes Everything.

Even his real name is Phainon. It’s Khaslana.

This is one of the things I did not notice the first time when the game was played – I ran over some dialogue like a dumb fool. However, it was there when I returned and rewatched the cutscenes. Phainon is really just a nickname, a mask I wear to conceal something far darker. And given that you have played Honkai Impact 3 rd, you probably just took a second look at this name. Khaslana looks very much like Kaslana, on the other hand.

Yeah, that’s intentional. HoYoverse is fond of their references.

But here’s where it gets weird. Khaslana isn’t a family name in Star Rail; it’s a title. A curse, really. It is the attribution of whoever happens to be the so-called hero of Amphoreus, forced to retell the same tale again and again. And by repeating so, I mean 33,550,336 times. That’s not a typo—a harv-load of cycles through the same tragic circle.

I cannot even play a game twice without getting bored, and this guy has played it millions of times.

So What’s This Irontomb Thing?

Ok, Irontomb is the place where my head began to melt. I initially believed that it was one more great evil villain – some Lord Ravager and his insane mess all over the universe. The IPC keeps talking about the assault by this elusive enemy they call Irontomb, and everyone is panicking.

However, by now, I’ve learned the real deal about Irontomb, and frankly speaking? It’s terrifying.

Irontomb is not really a person. It’s more like… a phenomenon? One of the destructive equations was underway, perfected. And Amphoreus–the whole world we have been strolling all around–was not created as a retirement or civilization. It was constructed as a laboratory, specially made to create and perfect Irontomb.

Every cycle, each restart, each time Phainon attempted to rescue his world? That was data. The system investigated him, learning where he had gone wrong, taking his agony to sharpen this piece of work: the Destruction Equation.

This disintegration of ItemD2R that describes how the Black Tide, or those monsters that rot everything, is actually a computational manifestation of Irontomb impressed me. It’s not fully born yet. It’s still being refined.

And Phainon? He might be the final piece.

This is the Flame Reaver Moment That Changed Everything.

This is an instance in 3.4 when Phainon changes into the Flame Reaver. I have already seen such a cutscene three times, and the visual narration is crazy. He is literally consuming himself from the inside out, channeling pure Destruction energy.

However, it is not only hot anime transformation stuff. The fire symbolizes what 33 million rounds of trauma does to a person. Phainon was required to gather a dozen more Coreflames each time with slain Titans and was convinced that he was finally gaining access to Era Nova new age, which would ensure the salvation of all people.

Spoiler: it never worked. Each time, the cycle failed at the very end.

One wants to imagine spending your whole life struggling to have a promised salvation which does not materialize. And watching everybody you love die, reset, die again thirty-three million variants of the same despondency.

Through this cycle, the one we are playing, Phainon, is hardly human anymore. This shows in the game through his dialogue, his expressions, and the way he discusses his burden. And when he became the Flame Reaver, I knew that I was not seeing a hero gaining strength. I was watching someone break.
