Sylva Awakened

Activate any of Sylva's six chambers (5U/s for 30 seconds), then head for the centre with a unit of Quartz in your pocket. At the core, feed the Quartz into one of the three raised platforms - a Geometric Triptych appears and the forcefield drops. Carry it across a bridge to the slot on the opposite side, click it in, and Sylva wakes.

The Odd Stone now teleports you between the engine and your active chambers (and eventually the satellite). Same dance on every planet for To Infinity... - only the resource changes.
