Edit: More Scenarios Because This Is Funny:

So we know that the White Star split the Dominating Aura and left a portion in the Forest of Darkness, right?

So imagine if the voice inside the Dominating Aura is NOT Choi Jung Gun (or some other ancestor) but rather the White Star's younger teenage self (before he becomes a Dragon Slayer/goes crazy), like Jour Thames is in the Rings of Life.

Dude has no idea what sort of maniac he becomes, is just a little shit constantly mouthing off against the other ancient powers in Cale's mind & keeps dissing/shitting on the White Star whenever they fight because he has no idea it's him. You know, cuz of the whole reincarnation thing.

Like I know the logistics here are a bit wonky (since I assume only Dragon Slayers inherit the Sword of Disasters and Dominating Aura once they inherit the title) but bear with me, it's such a funny scenario.

Barrow (lets call him that for now) would just be cheering Cale on the entire fight, thirsting for blood and suggesting pranks to play on the White Star. The funniest scene could be him rolling his eyes (metaphorically, since he's ghost) and shitting on the White Star for being melodramatic with terrible fashion sense. Masks? In this day and age?

Imagine him being horrified when he finds out what he's become, especially since he's firsthand interacted with Raon and the rest (courtesy of haunting Cale).

You know what would be even more hilarious? Imagine him just providing Cale some VERY intimate, embarrassing and awkward details that Cale brings up during battle just for shits and giggles to throw off the White Star.

Cale & the White Star fighting: Barrow, internally: Did you know I used to pee in bed every night until I was eleven? Cale, with a shit-eating grin to the White Star: So how did it feel to have such poor bladder control growing up? Eleven? Tsk, tsk. White Star, half-offended, half-terrified because this is just reinforcing his hare-brained theory about how the Gods sent Cale to kill him because how else would he know this: WHO THE HELL ARE YOU? Barrow, the little shit: During training, I once farted so loud the instructor called me ‘Thundercheeks’ for a month. Cale, visibly pausing mid-battle and incredulous: "Thundercheeks?!" The White Star, screaming in horror: Shut up shut up shut up!!!!

Every time Cale opens his mouth, Sayeru and Dorph lose a bit more respect for their master. Conversely, Raon thinks Cale is possessed (he is). Also White Star, babe, no Cale is not a reincarnator. Your archnemesis is literally you.

Just tinier, more gremlin, spiteful and hormonal. You know, a teenager.

Edit: more scenarios because this is funny:

Barrow, rubbing his imaginary hands: See that slight twitch in his shoulder? He’s about to dodge left. Cale: “Oh? So I aim right?” Barrow: “No. Compliment his hair. He'll blush. // Barrow: “Mention the mole. He hates the mole.” Cale: “What mole?” Barrow: “Inner thigh, left side. He’s irrationally sensitive about it.” Cale (literally yeeting a thunderbolt at him): “Still trying to hide the mole?” White Star screaming: “WHAT THE FUCK.”
