Transgretion

Kairo Velasco has always felt slightly out of tune with his own life — a quiet, persistent sense of wrongness he's never been able to explain. When an impossible crack tears open in the wall of a drainage canal near his home, he follows it without hesitation, and falls out of his world entirely. What follows is a fall through a string of alien realities — each one stranger, more dangerous, and more revealing than the last. With every world he survives, Kairo absorbs a fragment of its power: raw and uncontrolled at first, born purely from the need to not die, then sharper and more deliberate as the pattern becomes impossible to ignore. He's changing. Stacking. Becoming something he doesn't have a name for yet. But the deeper he goes, the more he starts to suspect the Rifts aren't random — and that something on the other side has been waiting for someone exactly like him. When a third Rift opens, larger and colder than the ones before it, Kairo feels it for the first time: he is being watched back. His origin world is already fading into memory, maybe unreachable. He steps through anyway — because the wrong frequency he's carried his whole life finally feels like it's starting to resolve into something. A note. A signal. A purpose. Riftborn is a portal-hopping progression story about identity, adaptation, and the unsettling comfort of finally fitting somewhere — even if that somewhere keeps trying to kill you.
