Soulweft

Every biological organism has a soul. "Soul" does not actually equal "moral value," even less so than "brain" does; in thinking beings, post-mortem consciousness is located in the soul, but in beings that never had any kind of awareness, a soul does not generate one. Souls of creatures more more complex than a bacterium are composed of filaments/threads of soulstuff. Complexity of soul scales with complexity of organism and power level of soul scales with time since organism and thus soul came into being.
