Perhaps the most beautiful and advanced sight in all of Aeternis, the orrery is a model of the solar system, made out of intricately designed brass, gold, and clockwork. It's an integral part of the test and requires all four shields to reveal access to the grail.
The orrery is a small, octagonal room. It is completely dismantled at first and requires activation. To do so:
- Solve the orrery puzzle. Rotate the semi-circles and move the star down into the center. The trick is to stop the star at the upper edge of the circles, then rotate them into position. This will cause the central rod to erect.
- Then simply flip the switch on one of the pillars in the Theo chamber. Mind you, one of them also releases the beast.
