There are many characters I love in lcf, and there are many relationships I adore.
But I think the relationship i love the most is (well okay maybe after the soos) cale's relationship with his ancient powers, and the way each of them somewhat represent a part of cale's personality.
Like in the crazy kid, cale's disrespectful-punk behavior and thevway he cusses and curses a lot, in the glutton; his appreciation of food, in the super rock; his determination to protect his family and the people he care for, in the crybaby; his fear of vicious people or hate towards the thought of getting hurt, in the cheapskate; his love for money and their crazy behavior when it comes to shitshow-ing, in the thief; his love for treasure hunting, looting and causing chaos upon the enemies' heads.
...etc etc etc. Cale is the mashup version of all these souls.
Additionally, they are literally a part of his soul. They kinda know about his past as Kim Roksu (at least some snippets of it), are fighting with him wherever he is, be it in an illusion or a different world, and are always with him 24/7, when he's calm, panicking, happy or sad, even when he doesn't understand what he's feeling.
It also hit me real hard when the super rock explained why Cale can still hear their voices, and Cale still decided not to absorb the ancient powers completely.
Because they're basically cale's only way out of his fear of being alone, because they are always with him no matter what, unless Cale himself dies or decides to take theor power fully in. And that was what made the wind island test 10 times more angsty for me.
He called out to them, but they were not there.
I also love that part when cale went to get the crazy kid's power and named her the sky eating water instead of the water of judgment; it was especially mind-blowing because unlike other ancient powers' trials, this one was actually really hard. And wasn't one mentioned in tboah. And cale was pretty much dying before obtaining that element.
Same goes with the wind island test where their past was revealed and the dots were finally connected– the western continent's past, how the super rock, the hero of the boulders and his friends were separated and died one by one in the mist tragic ways possible.
The super rock's wish for cale and his party to not be separated, it hurts more when you remember he had built the rock villa originally for him and his companions. His comrades he never got to live there with. But then gifted Cale and his family that villa.
Cale calling super rock the scary giant cobblestone at first was a great crack element in the story, hilarious to say the least, especially when he used to ask him if he was going to sacrifice himself. But then super rock told cale not to sacrifice himself when he actually answered yes, super rock's wish for cale not to end up like him, the lonely hero who sacrificed himself for the world.
Not to end up like them, like how him and his comrades did, separated and dying without each other's knowledge.
They are one of the reasons I actually believe lcf is going to have a happy ending. Because unlike the heroes of the ancient times, our Cale knows he should fight for his and his family's happiness, and not just for the world. To run away when it's really dangerous. Because Cale has them to remind him that sacrifice was never the right solution.
And I hope, through Cale and this timeline's heroes, these ancient souls would see peace and happiness after a lifetime of war and loneliness. Would experience what they never got to in their lives.
