It has travelled for millennia, drifting between worlds, observing without interference.
When the entity reaches Earth, it does what it has always done. It enters the nervous systems of living creatures and experiences existence through their senses. Instinct. Hunger. Violence. Order. Shame. Power. It does not judge. It observes.
From the depths of the ocean to the rise and fall of empires, the entity drifts from body to body, century to century, learning how this planet survives itself. It witnesses the birth of civilisation, the mechanics of authority, the cruelty of crowds, the intimacy of family, the seduction of belief. With each life it inhabits, something changes. Observation becomes preference. Curiosity becomes attachment.
And attachment has consequences.
