  • Look at the pattern this seashell makes. The dappled whorl, curving inward to infinity. That's the shape of the universe itself. There's constant pressure, pushing towards pattern. A tendency in matter to evolve into ever more complex forms. It's a kind of pattern gravity, a holy greening power we call 'Viriditas' and it is the driving force in the cosmos. Life, you see.
