Venus

After the OPA destroys its soldiers, Venus completes its work: a glowing tentacled structure larger than Ganymede rises, scatters the fleet, and flies off into the void.

Story so far

After Fred Johnson nukes the last hundred protomolecule soldiers in the Belt, the entity on Venus finishes its billion-year labor. On a live feed (delayed forty-seven minutes, from the ship Celestine) the Rocinante crew and Luna's assembled powers watch the dark side of Venus pulse like planetary lightning and then glow: vast iridescent filaments thousands of kilometers long, spokes on a wheel, light and vanish. Something enormous rises through the cloud cover like a fish surfacing under a tank — spoke-like tentacle strands arcing with lightning storms, joined to a rigid central node, larger than Ceres, larger than Ganymede.

It climbs free of Venus, hurls the watching ships aside (the Merman sent tumbling), trails a glowing plume of displaced atmosphere, folds its arms together, and accelerates away from the sun under no visible drive — swimming off into the void. The protomolecule has become something utterly inhuman and complete, and it has left. Whatever it was building, and wherever it is going, is now a new and open question hanging over the whole system.

Appearance

A vast glowing structure larger than Ganymede — iridescent spoke-like tentacles arcing with lightning around a rigid central node, trailing a sunlit plume of Venusian atmosphere as it swims off driveless.

Role

The shrouded planet from which the completed protomolecule structure rises and departs into the void.

Relationships

Fred Johnson — Whose nuclear destruction of the soldiers precedes the entity's completion and departure.

Prax — The botanist who watches its rise with awe and dread, unable to grasp its scale.

Avasarala — The strategist watching the feed as the thing she feared most leaves Venus behind.

Ganymede monster — The soldiers networked to it, whose destruction may have triggered its final act.

The world where the protomolecule fell with Eros — now stirring with intentional, inhuman purpose, disassembling ships that watch it.

Chapter 38

The protomolecule's crucible on Venus is confirmed to be thinking — its currents model a mind doing spatial reasoning, an alien intelligence taking shape.

Chapter 53

Venus spikes again — bigger than before and faster than light-lag — confirming the protomolecule is a networked whole that goes on alert when its kind is attacked.
