The Neon Veins are not a metaphor. They are a living current running beneath every biome, surfacing in cracks where the world has been wounded. Where the Veins surface, the laws of the biome bend: crystals grow, magma holds shape, vines speak, sand remembers footsteps.

The factions fight over surfacings. Bosses are drawn to them. Talent resonances align with them. The wise say the Veins are the world refusing to die. The paranoid say they are the world choosing who wins the next season.
